In a store, would you say something to someone who had a whole cart full of stuff at the Express checkout?"?

Today i was in Walmart and i got on the Express line. The sign said “Express: 20 items or Less”). Someone near the front of the line had a whole cart full of stuff – clothes, baby stuff, etc. While we waited, I saw him look at the sign several times, so he definitely knew it was express. When the cashier started to ring him up, I asked her for the manager. The cashier told me there’s nothing she could do about it. The manager told me the same thing.

When i got to the cashier to be rung up, she told me they can’t say anything about it, but what sometimes happens is other customers will say something to the person. She told me that one time she saw a fist fight over it, and that’s why they have the cops there. I had not wanted to say something to the guy for two reasons: one, because i did not think it was up to other customers to point out things like “hey, are you buying all those things? because the sign says 20 items or less.” my second reason was that i know myself, and i know if the guy was nasty to me i would definitely be nasty back and i did not feel like getting into an argument, especially because i know those arguments often deteriorate into “f…. you, f…. you” situations.

i am wondering what other Fluther members would do in a situation like that. would you say something to the person? to me, if someone has a few extra items it is understandable, but to have a whole cart full of stuff there’s just no excuse for.
