That happened to me last week at a drive-thru. I could've swore she said my total was $3.50. She sat there with her hand still out looking at me wierd and so I said "$3.50 right?" Then she says "$3.69" So I'm thinking what the?? As I drove away I realized she had given me the total
before tax (like an idiot!). But of course she played it off like I was the idiot!
(Note: I don't remember what the exact numbers were)
