Burger King review: Manager service and incorrect change being lied to and accused of lying

I just went to my local burger king on 45 north by tidwell in Houston Texas and ordered 2 plain original chicken sandwiches and 2 large fries and didn't get a total from the person who I gave my order to, just a mention about pulling forward to 2nd window. I gave the so-called acting manager some Hispanic looking guy in a black shirt a $20 bill and he gave me 2 $1 bills in change and no receipt, I didn't immediately think anything about it I just put the bills in my pocket with the rest of the change from the $100 bill I broke at fiesta 1 exit away at airline rd. I received $65.65 from there so I had 3 $20s and a $5. He brought the bag of food to the window I gave it to my wife and then pulled up a little bit and my wife said the 2nd fry was not in there, I u-turned right back to the drive thru but a yellow jeep wrangler was getting there order as soon as they left, I let the guy know I'm missing a large fry he told me that I only ordered 1 fry (yeah because me and my wife always share fries but not the sandwich) so he argued with me that I didn't give him a $20 and it was an older $20 not a new one either. I asked for what I ordered and what I obviously payed too much for. I was lied to disrespected felt like I just gave money away, I really need this issue resolved, I never have a problem with the daytime manager. [protected] Brian
