I also noticed those lightweights. I was also around at the end of the night and noticed the owner personally carrying them home himself. Guess nobody's leaving those laying around overnight security or not!

Speaking of security- save your receipts! I hadn't really bothered since most places are "all sales final" and then when I went to leave security gave me a hassle. Thankfully I happened to have it stuffed in my pocket. No way I was leaving without my stuff anyhow.
