I work in a busy bistro.
We had a customer email for a booking recently and listed a couple of dietary requirements for the booking, all fine, all normal and completely easy to accommodate.
But one of the diners was a "lacto ovo vegetarian".
Staff had a chat about this and our conclusion was this is a vegetarian who eats dairy and eggs.
Customers came, had lovely meal, and all was good. And left 5* TripAdvisor review 🌟.
So my AIBU?
Yanbu : you're right, this is a bog standard vegetarian.
Yabu : totes wrong this is some sort of Special Vegetarian.
