I used to have a regular customer who would come in every couple of weeks and bitch at me for not having a leaflet detailing all the products that are safe for people with onion allergies because it's such a common allergy.
Does he seriously think I can control that? Does he think management or even Corporate would listen to me? They don't listen unless and until someone with authority goes, "Dude, failing to post allergens could get you sued."
Never mind that the rest of us said the same thing for months...
And here's another rant. According to the dictionary:
Vegetarian - a person who does not eat or does not believe in eating meat, fish, or fowl, but subsists on vegetables, fruits, nuts, grain, etc.
Vegan - a vegetarian who omits all animal products from the diet.
The thing that really ticks me off are the people who say they're vegetarian, and then order fish or chicken or a soup made with meat stock. It makes life so much harder because you pretty much need to explain things every time.
If you don't eat red meat, okay. But you're not a vegetarian if you still eat chicken or fish. It's still meat.
It's also annoying when you ask about vegetarian options in a restaurant and the server asks if you eat fish. If I ate fish I wouldn't say I'm vegetarian because I'm not a freaking moron.
