Yeah, I used to care, but not anymore. The supermarket I go to most has perhaps the slowest checkers I've ever seen. TWO of them are transgender as well. All fat. The one MTF has these massive fucking fake nails so he can barely grab the items, and all of them grab just one item, swipe it, wait for the boop, put it down, reach for the next item. One handed, never picking up one item while scanning another. It takes fucking forever if there are even a few people in line. And God forbid if there are no baggers and the motherfuckers have to then bag your shit one item at a time. Like 90% of the time those fat tranny fucks are the only ones checking and I have too much shit to go through the self checkout (or booze), so I'm almost always mega-rustled.
You know who checks the fastest and I always get in their line if they are checking? A twenty-ish black dude with a Play (from Kid 'n' Play) style haircut. I guess he hasn't had his soul sucked out of his body yet like the rest of them, because he actually puts some effort into it. I always thank him for having some hustle too, and have even filled out the online comment card about how every single motherfucker there except him is slow as fuck, but I doubt it matters since they probably have seniority or they can't fire fatties/trannies easily.
