But you shouldn't be afraid of a SCENE, as you put it, in the US any more than UKY posters should be afraid of talking to people in shops or restaurants in the UK. Because aren't we always telling people that these things can happen anywhere? In other words, a SCENE is not the norm in the US any more than a rude barista saying they don't know what a 'moe-kah' is in the UK.
Shouldn't I?
Rudeness is absolutely universal. SCENES seem more likely in the US in my experience and in addition I'm more sensitive to a SCENE in a country that's not my own, in the same way that Americans in the UK are more sensitive to rudeness here as they're outside their comfort zone, or the level of what they consider rudeness/length of wait is not the same as it would be to the waiter.
At the end of a day I truly believe that a waiter in the UK might be quietly rude to me, or make fun of me in a conversation but the likelihood of one shouting at me and chasing me across a restaurant for a small transgression is very much less likely in my experience.
Despite having eaten in a restaurant or cafe nearly every day of my adult life in the UK, I've never had a raised voice from a server (I have had, drinks slammed on tables, or just waited ages for my bill, or rolled eyes etc), but in a much smaller sample in the US, I have on more than one occasion for what I consider small issues, such as leaving a 10% tip on very small check, pronouncing the word blueberry incorrectly, taking a second to work out what drink I wanted, or daring to complain about shonky service etc had raised voice admonishing or quite intimidating arguing, which doesn't quite constitue A SCENE but *could* easily therefore I am much more on edge with servers in the US than in the UK.
Partly of course, this is because I know where I'm going in the UK, and I'm less likely to be in tourist areas in the UK (although I do live in London and work on Tottenham court road, so maybe not), in addition I'm more culturally au fait with the UK I'm much less likely to make a small transgression and therefore less likely to get into a SCENE.
In terms of a SCENE I've actually remembered another SCENE. I was at a very expensive steak house in NYC last year and the service was absolutely shocking, it included the bill being dropped on my HAND (in a tray) whilst I was still eating my dinner, I called him back to talk about the all around terrible service (in a nice way) and the server told me that he'd been busy as he had a table of "Those chinese people and you know what they're like" then rolled his eyes and went "What do you want Lady, you GOT YOUR FOOD?", he then just walked off, then the head waiter came over and was like "YOU PEOPLE ARE COMPLAINING" really loudly at which point the entire restaurant is looking, my DH is getting seriously pissed the waiter is firing stuff at us loudly like "you got your FOOD, You just don't want to pay the BILL" as we try and outline the problems, and with me attempting to make everyone calm down before the restaurant manager finally realises the entire restaurant is now looking, the people on the next table are chiming in and I just want to DIE.
At the end of the day, it's just how I feel. Rudeness, everywhere, SCENES, more likely in the US, for a number of factors, some of which are related to my status as a non native.
