I'm not in US, but here in my part of Europe it is common to leave a 10% tip when eating in the restaurant (though nobody will complain if you forget). Some restaurants will collect 10% service fee if table was sat by more than 5 persons. I quite often order food through apps like wolt or glovo and always think twice when going through "tip" section. First- the app asks for a tip before I receive service (even though uber eats used to state that tip can be cancelled). But what makes me more curious is if courier knows about tip, or is the tip included in fee collected so higher the fee more couriers are interested to take the call.. I also have local pizza shop, whenever I order pizza there I tip delivery guy even though he does not, in any way, makes me to do so. I do it more eagerly if there is bad traffic outside or bad weather, basically being happy not having to drive/walk to collect the food..
