The first entry is always the most painful.

I find it completely hilarious that people, when at shops or the like, can be so disrespectful. It is a dangerous thing to do, a clerk will always find a way to get vengeance. Be it messing with your food, or outright confrontation, there will always be a time when a clerk simply just feels the need to let lose in a blaze of foul language, or simply messing with the customer. Like not giving them a receipt, or floor salt, or simply messing with them by inserting the word penis randomly into conversation, and making it seem like you have tourettes. For a creative, disgruntled clerk messing with the general populace is a fine art, not unlike calligraphy. When i worked at a video game store that rhymed with lame shop, I discovered one of the most fun things to do to those asshats that come in and show no respect is pretend you're deaf, they feel bad, and most for some reason speak louder. Another instance was to randomly whisper blut on the phone if a customer called. Yes i was one of those angry clerks, the ones you hated, and loathed, but like the tag line of clerks says, just because we serve you doesn't mean we like you.
