Doesn’t Like His Veggies (Questioned)

(One of our most popular sandwiches is our BLT. Our veggies are optional, however, so some people do not get lettuce and tomato on their sandwich. We just normally ask what veggies they would like on their sandwich. A mother and her teenage son walk in and go through the usual ordering process.)

Me: “Any other sandwiches for you guys today?”

Mother: “Nope, we’re good!”

Me: *asking the son* “And veggies on your BLT?”

Son: “…”

Me: “Veggies?”

Son: *rolls eyes and speaks in a very condescending tone* “Well, lettuce and tomatoes, duh! God!”

Me: *stays silent and proceeds to put veggies on his sandwich*

Mother: “CUT THE ATTITUDE, [SON]! She’s not a mind reader! She doesn’t know what the f*** you want!”

(At that point my coworker and I had to hold back our laughter while the son slowly turned red from embarrassment.)
