Been waiting for an opportunity to tell this story here ...
Toward the end of a 12 hour car trip and late at night (should've been 10 but there was snow) I stopped for gas, coffee and relief. Went into the first restroom door I came to, didn't even look at the sign (which was on the wall a little ways after the door, btw).
I didn't realize until I saw that little metal bin on the side of the stall. I was so tired the thought process was like - hmmm, that's a container they usually have in the women's room ... I wonder why they put one in here ... wait a minute ... I don't remember seeing any urinals when I walked in ... OMG! I finished up fast, not wanting to be caught with my pants down (literally!). As I exited I glanced at the sign, threw a verbal "sorry" into the air and headed for the coffee center.
I quickly got my coffee and went to the counter to pay. The female cashier said I didn't have to pay for the coffee. I thanked her and left, not knowing if the coffee was free with a fill up or because she saw what happened and thought it was funny. :)
