Appearances are deceptive
I found myself in a part of Coventry that looked like a set from a zombie apocalypse movie. No cafes anywhere and only poor quality vending machine drinks to pass the time whilst waiting for a car fix.
Eventually I needed to use 'facilities' not present at the garage and wandered into a very rough looking and almost totally deserted pub. A bloke behind the bar, seemingly made entirely from tattoos and piercings, asked me if I was lost.
I asked him if I could use the toilet. Sure, he said, I'm just unlocking. Facilities were basic but weirdly had Molton Brown handwash and clean fluffy towels.
I "didn't suppose" they did coffee there, and the chap laughed --- not much call for it, he said, but he went into his own kitchen and made me cup of instant. No Wifi either, --- but if I didn't mind sitting at the bar, he'd put his phone in tethering mode and I could use that.
Being a bit of a big fat bastard, and with a few years of kung fu under my belt, I'm usually a bit less intimidated by rough-looking people than many of my peers. But, in my experience, unless you're really out of order, you're much more likely to encounter serious unpleasantness at the other end of the spectrum, even if the language isn't quite as fruity.
