stolen 1980 Firenze GL-2000

Left my bike inside Ralphs while picking up groceries. I usually chain it outside to the bike rack but was unable to find my chain this day. Security was on duty at entrance of store. Bike gone as I exit. It may not be related, but peculiar events leading up to a crime might be noteworthy. In this instance, the only two lanes open are furthest from store exit, which is typical, but I was held in line approx 20 minutes by single customer who apparently couldn't decide what food he wanted / what he could afford, juggling items in and out of a cart. Cashier continually voided and provided multiple receipts to demonstrate totals. Another woman shortcuts all shoppers to personally pay the cashier for bananas. At this point it felt like I could be on candid camera. Another woman with her child gets in line next to me and stares at me noticeably. I acknowledge her and she keeps staring. Right before I check out security walks by towards rear of store with another employee looking confused. I check out, go to exit, can't find my bike. Security returns as I'm looking around and tells me he can't always be at the front, sometimes he has to go to back, and that "that guy was watching, waiting for me to leave to take it." This struck me as odd. I'd only asked if he knew where my bike was at. When asked if they have security video, he said no. I say that can't possibly be true. He replies that I have to file a police report. Also, the cashier seemed flustered and impatient when ringing me up, bagged my food then asked if I want any bags. I don't know these people personally, but I am in the store a few times a week and they are familiar faces that have otherwise been kind.
