Some hipster cunt tried this on me in Switzerland last week after charging me 5chf for a coffee
It's your fucking civic duty to press "NO" and get straight on Google maps, TripAdvisor whatever and leave a 1-star review for even attempting to normalise this shite
I can't be fucked leaving the reviews but it will always be the last thing I buy there.
If Americans want to do this shit that's up to them, I'm not paying the bar keeper 10% for pulling me a pint. If it's my local, I'll offer to buy them a drink now and again, I'm not doing that in a pub I may only go to once.
Reviews won't change anything in the US until we eliminate "tipped minimum wage", and raise regular minimum wage to something that would allow a minimum wage worker to conceivably reach the poverty line.
