No.

Merchants usually will set a closing grace period from store operation hours. So for example, if they close at 2200, the grace period is 1 hour (example) before closing so orders will not come in 1 hour before closing.

FoodPanda is 1 hour before closing.

But Grab does manual work, so the key account person has to update the system manually on the changes of operation hours, with MCO in place etc. Unlike FoodPanda where they have a portal for Merchants to change it from their end to avoid this mess.

Its either Burgerlab did not communicate the new time to Grab or Grab screwed up on the operation hours.

I thought mBL is exclusive to Grab?

But yes, both parties to be blamed. Only a handful of stores also cannot handle. Incompetent.
