I swear I read somewhere that there are parts of Europe were tipping isn't required, but if you want extra good service you'll tip before being served if you want good attentive service.
Please correct me if I'm wrong, I can't remember where I read it.
At least in my part of Europe, tips are not required and often not expected (because minimum wage doesn't have the strange exception tipped employees do in the US), but if you actually appreciate the service given then it's the norm to give a small amount as a tip.
For deliveries I normally give cash straight to the driver if it comes in a reasonable time frame, I certainly would never preload a tip using the payment portal
Ended up having the driver yell at me to come get the food in the lobby and that I was wasting his time when I was sick with covid and even though I specifically ordered for door delivery.
On top of that the food was cold and soggy. So I went straight to customer service and removed that tip.
If I have cash I will tip if they do a good job otherwise. No.
One night a while back I ordered some food from a place about 10 minutes away after a long day with a sick baby and tipped ~30%.
While the drivers at the restaurant I got like 5 messages asking for a better tip, I didn't answer because why would I. Then my foods on the way and on the app it looked like the guy parked down the street for 10 minutes and continued to spam me with messages asking for a better tip. I didn't respond because why would I. Then the food gets here, I'm hype. I have very simple delivery notes on every order "Please don't knock or ring the bell" and always do leave it at the door. I pulled up my security camera to see this guy just going in on my doorbell (which is disconnected anyway), then he starts slamming on the door yelling variation of "come get your food". After a few minutes of that he just puts the food on the step and starts yelling a bunch of stuff out front of my house at like 9pm, including again asking for more of a tip. In this time he set off my dog who's now losing his mind and woke my sick baby. So naturally I put my dog on the leash, grabbed my crying baby and in the most redneck b horror movie fashion I could muster flung the door open and just stood there on the step with a crying baby, a 100lb dog going nuts and the defeated eyes of a father who just wanted a cheesesteak after a long day.
I said all that to support, how I didn't get to eat my food until hours later because now I had to soothe my baby back to sleep. Their response was something along the lines of
'Hi ***, sorry about that. Here's a 4.63 credit as an apology. That's 20% off your order total!'
Moral of the story is now I always keep a few quick meals in the house that cook in the toaster oven. It's cheaper and the toaster oven never woke my baby.
