Never consistent.
I was in twice this week. On my first visit I ordered a potato, chicken nuggets and a kids size frosty. I paid at the first window and when I reached the second they tried to collect money from me, when I informed her I already paid at the first window she asked if I was sure that I already paid. I wasn't OK with her implying I was lying about paying for my lunch. After all that confusion they handed me my lunch, told me to have a nice day and I drove away. One I got about 10 feet ahead I realized they never handed me my frosty but at this point it was too late. A car was already at the window and since it's lunch time the parking lot was a disaster and I wasn't going back.
My second visit was yesterday, I ordered a kids meal but it didn't have a toy inside. While this isn't a huge deal to me since it was for myself. But, if I had a kid in the back seat waiting on a toy, I'd be pretty upset.
In previous visits I'm usually missing an item 2 out of 5 times. Whether it's butter for my potato, dressing for my salad or a straw for my drink.
