Too aggressive. I wouldn’t call it a bribe. Your comment is confusing to most People. Bribing is nefarious and/or illegal. Like bribe to get out of a fine or a bribe to get some government agency to approve Something

This is a fee for service.

Not my comment.

And maybe not “most” people. I understood perfectly well what OP was saying.

No, a fee is an upfront amount to do a task.

The fact that is it nebulous, and if you don't put a number that's considered big enough (by someone elses judgement) then you won't get your food delivered puts it beyond a "fee".

Well those platforms call it a tip, not a fee for service, so they're already being dishonest and nefarious.

And I don't personally know anyone who wouldn't consider it a bribe, except for one or two pedants.
