    they forgot my plain cheeseburger that i ordered for my dog in the drive thru (5:46pm) so i went back inside & told the guy at the counter. he then told the pink haired girl dressed in black who yelled to grill to make one & responded with, “there WAS a plain cheeseburger in that bag. i put it in there myself.” clear as day, loud enough for everyone at the counter to hear. the nice guy came back & told me it was being re-made. i told him “i swear there wasn’t one in the bag,” to which he apologized. moral of the story, i assume she’s a manager & she needs to watch what she says & where she says it. i don’t appreciate essentially being accused of essentially stealing a freaking plain cheeseburger for my DOG to eat. it was the cheapest item out of my $20+ order. this location already has a bad reputation for screwing up orders as it is, so the attitude from the employees when i was already overlooking a mistake isn’t appreciated.

    I was here celebrating my granddaughters birthday, and watched a younger maybe 14/15 years old, told to sit and wait for interview, 40 minutes later manager finally came out and told her she dont have time and told to leave. No wonder no one wants to work.
