Gay, trans, Vegan, Gluten free - you name it, someone wants to be identified by it.
Reason for the whinge? Bloody customers.
I now sell curries and the increasing number of people coming in asking 'is it gluten free', 'does it have any nuts in it', 'is it dairy-free', 'do you use cooking oil' and, just the other day 'do you do 'nightshade free' meals'

It was bad enough when the welly-brigade came in announcing to all-and-sundry " I'm a vegan....." (as bad as those that feel obliged to tell you "I have an iPhone"..... big effing deal) but just the other night I saw a TV article where some restaurant owners were JAILED for serving a meal that had nuts in it to someone with a severe allergy (who sadly dies as a result).
What nutcase, with an allergy so severe that it could be life threatening, orders food from somewhere they have no intimate knowledge of? I'd be too sh1t scared to eat anything I didn't prepare myself let alone have some non-reflective cousin take my life into their hands. WTF?
I'm almost tempted to do a Gordon Ramsey on customers that ask (or state) such requirements "we're a restaurant, not a f****g doctors surgery" - but I'm far too polite to be so straightforward!
Anyway, in light of the jail sentence passed down, I can see take-away's now refusing to serve food to anyone with ANY allergy whatsoever OR they should (as I'm tempted to do) demand a 'service fee' for dealing with the kitchen uproar that catering to such minority needs requires - cleaning down, fresh tools, etc - basically the extra time needed to make their food 'safe'. Call it an extra £75. Per meal.
Nightshade free - I know you're asking! Apparently no peppers, no tomatoes.

Reminds me of the time I was being arsey in a hotel breakfast restaurant:
Me - Full English breakfast please....... no tomatoes, no black pudding, no bacon, no sausage, no beans, no hash brown.
Waitress - How would you like your eggs?
Me - Boiled.
