I thought it might be kinda close to incident. Them's appear to be some drunk folk. Although, a simple rule to keep mind of when making things others will use: don't assume others will have the same wits about them with it that you do yourself.
(For example, my soon to be ex-'girlfriend' asked if she could have some of - what is now - my ice cream. I said sure. I went and looked at it, later, and the top was all pushed in. Can't dig it. Incidentally, though some may think I'm lying or something, she's not having me out, but that I need to live alone - for obvious reasons.)
