Heavens to Betsy, does it get any worse? C'mon let's see.....

I was just in the convenience store grabbing a coffee and paper before work, and in walks an old man wearing ratty pajama bottoms, corduroy house slippers, and a white (well, we'll call it "off-white" with the understanding that I'm being generous) undershirt that did not fully cover his belly. Now I'm all for comfort, and flying your freak flag and whatnot, but shouldn't there be a line somewhere? Doesn't basic respect and decorum require that you put on a pair of damn pants if you're a grown-ass man out in public? I'm asking. If you tell me I'm wrong, I won't start stepping out in my housedress and curlers, but I'll try to judge those of you who do less harshly.ADDED: Here's one where I won't entertain argument. When you call a business, identify yourself.
