Whataburger complaint: Organize

I went through the drive thru as I have thousands of times over the years. Ordered a number 2 with mayo and no pickles. Paid at the first window as asked and the sign said was given no receipt. 5 minutes later I’m at the second window I’m asked for my receipt and I told the person I wasn’t given one. I was then asked what I ordered, then asked if I paid then asked what I ordered 2 more times by 2 different people was still given no receipt or asked if I wanted ketchup whataburger used to be so great with customers and no it’s this. Maybe I’ll try another location in the future but I’ll surely go somewhere that knows what I ordered 5 minutes after I ordered it and wont ask 4 times maybe you need to invest in some software like chic fil a or raising canes has that knows my order when there’s 20 cars in line. I have my food but still no receipt. Maybe you should have better training or sell the company back to the Texas family who started it and knows good service
