You are talking about all the bullshit that requires assistance now aren't you? I don't even buy alcohol and some stores will require me to wait for assistance for multiple items every time I go in. Unfortunately, these are also the stores where they no longer have cashiers at all.
Paint and shit kids might huff... I can understand, there are laws after all, but random high theft items? The fact that I scanned it at all should be a clear indicator that I am not trying to steal it you dumb fucks.
