This place was ridiculously slow are mom had repeat her order five times for the lady to get it and it took us 20 minutes to get our order and there is no other people in line So am I had to ask if we should move forward and the rudely responded

Can you be more specific about when this occurred. This DQ has a new owner this year (2019) and from what I have seen, it is operating much smoother than late in the 2018 season.

I have never went there and not come out completely in awe of the lack of customer service, the wait, and the poor food quality. I reported it to DQ headquarters, but its privately owned. Maybe if enough people call, they will revoke their license to use the DQ name.
