Kwiki Mart rest-room

I do a lot of traveling as part of my weekly routine, and much it is spent on long stretches of highways and other connecting roads, and I am forced to stop at many out of the way type gas stations to relieve myself. Frequently the bathroom door is locked and the key must be obtained, of course this means you have to be handed a grimy fly swatter from some Arab who can barely take his attention away from the satellite cast Aljazeera T.V long enough to help you. I recently reached my breaking point when I went to an Apu style mart and asked to use the restroom. I was given the grimy key and preceded to the restroom conveniently located on the opposite side of the building. Much to my dismay, and I should point out that I really had to go, the door was jammed and would not open. I finally went back inside and asked about it, where I was told that door was tricky and required some shaking and pulling. I tried this terrific advice in the exact order I was told, I shacked, pulled, and even did some prying, but it would not budge. Upon my third trip inside the store the kindly foreigner finally agreed to escort me to the door and try his own hand at opening it, after some shaking, pulling, prying, and some rattling the door finally opened. Inside was the most horrifying filth ridden excuse for a toilet that I have even seen in my entire life! My question is this: Why are you locking this door? Clearly it isn’t to keep the filth out. Are these gas station trying to keep the dirt locked in? Maybe it’s a public service, keeping all that disgusting bacteria from reaching the outside world. Whatever the case may be, it’s way, way, way too much trouble to take a piss. I will never buy anything at a station that does this, it’s absurd.
