It drives me wild when places say, "NO BILLS OVER $20 PLEASE" or "NO BILLS OVER $50 PLEASE", sometimes without the please. I see a lot of McDonald's with the $20 request. For each of these vendors or places with these stupid signs, I just have to say one thing: Money is money, I'm giving you my business, now shut the f*ck up, take it, and give me my change.
