Convenience?

Every so often I frequent a convenience store, just to remind myself why I avoid those shitholes. Yesterday I made one such visit to the BP/Amoco close to where I work. With Coke and a Snickers bar in hand, I approached the only register that appeared to be open, the clerk appearing to be a 70 something trainee, and having a tough time. The other register was open, though I didn't know that, and nobody bothered to tell me. The clerk in charge of that register was helping the trainee.

When another customer approached the other register, the clerk stopped helping the trainee and waited on him, despite my having been there first. I took a deep breath, tried to be patient. While the trainee still struggled to find the buttons on the register, however, another customer approached the other register, and was waited on. Nobody even made eye contact with me. I politely set my coke and snickers on the floor where I stood and walked out the door. Now I remember.
