Sonic Drive By

So, not much has been going on lately, the usual waste time by sitting around, of course, but nothing new. I've downloaded some mods to some of my games and found fun in that, but honestly, nothing exciting has happened lately.
To give you an example of just how boring my life in college is, I offer you an amusing anecdote:
Me and my two brothers from a different mother went looking for furniture yesterday (yes, barrels of monkeys. I told you.) And after our weekly trip to Wal-Mart, we stopped by our local Sonic Drive In for some tasty treats. As we pull into our parking spot, we notice that the car hops are actually on skates at this location and we get excited at the nostalgia that ensues.
After ordering our meals, we were surprised to see how quickly our food was on its way. We recognized our delectables on a tray carried by a car hop who seemed uneazy to say the least on skates. Coming off of the curb toward our vehicle, she annouces that she in fact isn't comfortable on skates which seemed to set off the Rube Goldberg of events where she then proceeded to tumble with our tray of treats, my friend tries to grab her from his safely buckled position in the car, she gets turned around and rolls backwards toward the street before stopping and tossing our Route 44 Coke into the air and onto the ground. She then professed her embarrassment and confessed her hatred for skates and her disdain as to why the management makes them wear skates.
This leads me to wonder why they did, as well, but as we started looking around, it didn't seem like a requirement. Not all of the car waitresses were on wheels. She, wasn't alone, though. A friend from high school who also worked there as a car hop was on skates, however, her moves were much more graceful than Ashley's (our car hop). Was she just the target of a Sonic initiation? a hazing? a joke? Who knows. Perhaps the management of our local Sonic has a better sense of humor than I gave them credit for. Perhaps the "security cameras" they installed were actually for capturing the tumbles of their employees and then secretly sending them in (in medley form, of course) to some practical joking, hidden camera prank show. The skates, although providing a heavy nostalgic feeling of comfort can produce the negative effect when burgers and tots go flying through the air landing all over a customer's car. Can someone set me straight on the conspiracy behind this?
