One time.
My friends and I partied all night and were low on cash the next day. I assured them I knew the bus system and which bus would get us back to where we needed to go. We passed out on the bus and woke up at the bus station. It turned out, it wasn't the right bus and the bus station we arrived at was in the opposite direction that we needed to go. So, I called my girlfriend (wife) and she translated what had happened. The bus station felt sorry for us and gave us tickets to drop us back off where we got on.
Suffice it to say, we didn't wait for the right bus and took a taxi back instead. It was a good 2-hour nap, so at the end, we were all just hung over and wanted that taxi to get us back as soon as possible so we could get in bed.
