Not Eggsactly Dairy

(We had just gotten a special order for a sandwich without cheese, with the customer telling us she had lactose intolerance. After having made and sent out the sub, our shift lead comes up with this gem:)

Shift Lead: “So I was wondering something. She said she’s lactose intolerant, right?”

Me: “Yeah, that’s probably why she didn’t want cheese.”

Shift Lead: “But she still got the mayo.”

Me: “Yeah…?”

Shift Lead: “Mayo has eggs in it.”

Me: “…okay. What does that have to do with lactose intolerance?”

Shift Lead: “Well… I mean I know sometimes eggs bother me so…”

Me: “I’m still not sure what one has to do with the other. Mayo doesn’t have milk in it.”

Shift Lead: “Yeah, but it has eggs!”

Me: “That still has nothing to do with lactose intolerance.”

Shift Lead: “…”

(My best guess is she thought eggs were a form of dairy. I guess that means I’ll have to start watching out for egg shells next time I have a glass of milk.)
