Walmart checking receipts....

Don't know if anyone has ever brought this up here, but how do you feel about walmart stopping everyone to check receipts? Do you find it annoying? A waste of time? Does it not bother you or your SO?

Personally I understand why they do it. They lose money with each theft. It's also sort of annoying to me. Especially if I'm in a hurry and have to stop to get my case of water scanned. I could understand if people are walking out with high dollar items. It just sucks when they literally have a line to leave. But again I do get it. So what's your vote/opinion on it?
