I spent a night at a big motel with a huge parking lot. Took the dog for a walk around the area and saw lots of self-tapping sheet metal screws laying around. Began picking them up and when I got to all I could hold in one hand, (maybe 50 or so), stopped by the office. Handed them to the clerk and suggested they get someone with one of those magnetic sweepers that can clean a lot like that in 10 minutes, else they are going to get lots of complaints from customers. They brushed me off appropriately.
I checked around my new pickup with 200 miles or so, checked all the tires and all was well. When I backed out and left, was VERY careful to go slow and look for screws.
4 hours later 100 miles down the road TPS light came on. Checked the suspect tire, sure enough sheet metal screw so far to the edge no one would be willing to plug it. Fortunately I had a compressor with me and aired the tires every hour and could make it home. New tire = $389. Filed calm nice claim with motel, including pictures of screws in motel lot, screw in tire and handful that I handed their clerk. Got nice response - should have read more closely their sign in the office that they are not responsible for any bad things that might happen if you stayed there.
I guess my point is that bad stuff happens, frequently in suspicious groups, but it's just life, suck it up and get on down the road.
