Tipping is NOT omnipresent in the European capital I live in. Of course some apps have tipping options but I never found correlation in service quality to tipping. On the contrary, when I tipped, service quality was “less optimal” and I noticed visible entitlement.
That being said, it is cultural norm here to tip by rounding up the order(say total is 2.59/ you tip by asking to make it 3.00/) when you are ordering in person and the service is/was good and the food is/was also good quality. Alternatively, in some restaurant, it is not usual to tip as order is collected by someone near the cash register while served by someone else entirely and someone else is preparing it. Once you are done eating, you return the dishes and go home, so there is no option to tip as you simply don’t tip at the prepayment step because you don’t know the food and service yet, you don’t tip the server as they simply bring the food and walk away.
I don't know why both replies are about tipping when I didn't mention it at all. I meant these delivery drivers are everywhere. I've never used these data-sucking app so I don't know anything about them.
