OK Nettle this is just for you. I hope it meets your requirements.
Neil Pearson was a pain in the neck in the Drop The Dead Donkey years, early 90's IIRC*. He appears in a number of lists for this time period apparently.
Back then, the place I worked was the only coffee shop for miles. Starbucks was unheard of outside Seattle.
He kept ordering a latte then sending back because it was 'wrong'. On the third return, my colleague gently referred him to the 20 choice coffee menu to check it was actually a latte he wanted, (as what he was huffily describing was not a latte but a cappucino).
Menu thrown down, 'Do you know who I am?' demanded loudly enough for the whole place to hear.
My colleagues' response of 'No. Should I?' was a delight. It caused him to leave in a dramatic swirl of cashmere fury.
*Disclaimer: maybe he was a method actor and was in character. I had not and have never seen DtDD.
