When I was in New Orleans recently some buskers had Venmo accounts which I thought was a neat progression, for lack of a better word.

The Edinburgh Fringe introduced a tap-to-tip system this year, based on iZettle readers in nice-looking Plexiglass stands. The readers are preconfigured to debit £5 from your card on a tap. That's a bit more than your average street show tip of a pound or two, but really good if you're wandering around without any change - you don't have to feel guilty about watching a street show but not being able to pay at the end.

Canadian here. We tip 15% on almost everything but also pay by card most of the time. What happens is that machines have three quick press buttons (10%, 15% and 20%). You can also press the "tip $" button and enter the amount you want. Once that's done, you simply tap your card on the pay-pass machine that the barman presented to you.

That being said, I've not given money to an homeless person in ages. Whenever asked I simply answer "I only carry cards, sorry" and they immediately lose all attention towards me.

Tipping's not a problem, when they present The Machine you type in the tip you want.

>And tipping at bars etc can be harder too.

That's not too much of an issue in Europe.

It's certainly a bit more of a pain if you're paying with card. As noted in a sibling comment, it's pretty uncommon for bars to allow you to run up a tab in a lot of places in Europe. I lived in Sweden for awhile recently and out of the many bars I went to I could only think of one or two in the entire nation that allowed me to open a tab. So you have to do the whole song and dance with typing in extra every time you go to the bar (assuming the card machine is set to allow it, some aren't). There isn't even a guarantee that the extra amount will go to the bartender, so your best bet is to just tip in cash. But wait! a lot of bars in Sweden for example don't even accept cash.

My point being that it is out of the norm to tip for drinks in a bar.

How is tipping at a bar harder? You just write on the bill what amount to want to tip when you close your tab.

Bar tabs (in addition to tipping culture) are less common outside of NA. It is however quite common to leave the change from say a £5 note for a £4 beer. This is purely down to the convince (no need to wait for your change) and frictionless nature (the bartender already had your tip) of the transaction.

Write with what? I've yet to see a single restaurant put a pen next to bill. What I do is I leave the cash after card payment. Seen the option on card reader for tip maybe 2-3x in my life.

You don't need to tip at bars when the law mandates all workers have to receive a livable wage.

I understand that this issue is a sensitive one and there is a great deal of justifiable criticism of tipping culture. However, this comment is snarky. We all know that many countries have higher minimum wages in place of a culture of tipping. The person to whom you responded is not responsible for the prevalence of tipping where he or she lives and there is no reason to be reductionist, accusatory or otherwise snarky.

This is the case in many (most?) states in the US as well.
