This happened to me just today. Went to the whistle stop in Pasadena CA and the guy followed me around d like I was going to stick a bunch of track down my pants and walk out. I asked him a few questions and he was short and sassy, I wanted to lay into him, but didn't.

Went to the Train Shack in Burbank 4 times in the last week, each time with my two young kids, never frowned, happy to help, and even gave my girls a magazine and some train crackers.
