Earlier this week I bought breakfast from the cafeteria at work. Something I rarely go.

I get a bagel with cheese and a coffee - my standard breakfast out. It was a morning I was tired so I got the extra large vat-o-coffee. I was expecting this to be around $3.50 give or take (this cafe tends to be pricey but it is in the lobby of the building where I work etc etc).

Rang up at $5. Significantly more than I expected. The cashier said that was because I had a large coffee. I just stood there processing.

Finally she realized I was not going away. I think that was when I asked how much the bagel was.

She then took the time to ring it in again. It turned out to be $3.50 (I never did mention that figure to her), and I ended up with apologies and $1.50 more in change.

A good lesson in taking the time to figure out your bill rather than accepting there word for it another solution might be to always get a receipt - this cafe normally does not give receipts other than on request.
