Heavy rain in Singapore often brings a familiar wave of customer complaints across social media and delivery apps. Orders take longer to arrive, riders appear stationary on tracking screens, and stacked deliveries become increasingly common during peak storm periods.

Behind those delays, however, many Foodpanda riders say a separate problem has been quietly building for years.

Across unofficial rider Telegram and Facebook groups, couriers have repeatedly raised concerns over what they commonly refer to as the “$3.21 issue” — a phrase that has become shorthand for broader dissatisfaction with how stacked-order payouts and rain surge incentives are calculated.

Riders say the frustration centres on a perception that stacked deliveries during rainy periods frequently return payout figures close to S$3.21, regardless of the actual distance travelled, the number of pickup and drop-off points involved, or the additional time spent navigating poor weather conditions.

The issue has become especially contentious during storms, when Foodpanda’s app promotes rain surge incentives and multiplier bonuses intended to encourage riders to continue working despite hazardous conditions.

Many riders say they accepted difficult rainy-day jobs expecting those multipliers to significantly raise earnings in exchange for the added risks associated with flooded roads, reduced visibility, slippery surfaces and lightning exposure.

Instead, some claim the compensation shown after completing stacked deliveries often appears disconnected from the actual workload involved.

According to riders active in community discussions, the problem is not necessarily tied to a single payout amount itself, but to the perception that payouts remain unusually similar across jobs with very different travel demands.

Several riders also point to confusion inside the app’s job classifications. Completed deliveries, they say, can sometimes appear labelled as “Single delivery” while simultaneously indicating they formed part of a stacked order.

For riders already questioning how the system calculates earnings, those inconsistencies have added to suspicions surrounding payout transparency.

The concerns appear to be affecting rider behaviour during bad weather periods.

Some riders say they now routinely reject stacked orders they consider unprofitable. Others wait for better-paying jobs rather than accepting deliveries immediately. A number of riders openly question whether it makes financial sense to rush through dangerous weather conditions if compensation does not appear to meaningfully increase.

That hesitation can create knock-on effects across the wider delivery network. Orders may be reassigned multiple times, restaurants experience longer waiting periods, and customers face growing delays as available riders decline jobs.

Customers often direct their frustration at riders themselves, though many riders argue the underlying payout structure is contributing to the slowdowns.

According to riders involved in these discussions, complaints over stacked-order compensation and rain surge calculations have surfaced repeatedly over several years through support tickets, escalations and rider community conversations. Some say the matter has also been raised in discussions involving the National Delivery Champions Association.

Riders say they still lack clear explanations on how rain surge multipliers are calculated, how stacked-order compensation is determined, or why payouts can appear inconsistent with the total distance travelled.

The issue has also widened into a broader debate about transparency within platform-based work systems, particularly when riders cannot independently verify how earnings are generated.

As Singapore continues examining protections and standards for platform workers, some riders believe the payout concerns deserve closer scrutiny from policymakers, labour representatives and the media.

For many within the rider community, the “$3.21 issue” now represents more than a disputed payout figure. It reflects a growing disconnect between platform messaging and rider experience during some of the most demanding delivery conditions on the road.
