I used to eat lunch with a guy that almost always ordered a BLT. One day, there was mayo on only one slice of bread. The day after, he requested mayo on both slices. When the bill came, they’d charged him an extra dollar for the mayo. He made a point of telling the cashier that the dollar came out of the waitress’s tip.
I once ordered Fish and Chips at a decent enough restaurant. It came with two sides and so I ordered two sides.
When my meal came with the fish and the two sides BUT NO CHIPS - I questioned why? Where are my chips (fries)?
The waitress said I didn’t order fries. I couldn’t believe I had to explain to her what Fish and Chips are.
They ended up bringing me my chips.
