Alamo not uncommonly did this in the past. I got billings twice. I knew there was no damage by me on the second time as I took photos and some camcorder stuff. I told them that. bottom line, I was certain I did no damage and paid zilch extra. Dig up the return bill they give out with the time, date cost etc on it. If it does NOT state damage you or your buddie should be ok.
