Drive through is handy. As I am a new customer to the shop, early mornings have proven best as employees always get the order right and when I am early enough, they have time to make recommendation on what is good. Never have any problems in the morning.Afternoon this week was a different matter, had a long wait time and a long line formed behind us. When we got our large drinks there was maybe about a third of the large cup filled the coffee and a lot of foam trying to cover up the problem. I recognized something was wrong when the older guy handed the cups to me, so drove around to the front and parked and actually look into the cups. Sons took them inside to ask what the deal was as all the cups were nearly empty.Guy made excuses about new employees, and a lot of people quitting lately, but the light weight of the cups were obvious, there was no way he did NOT know they were mostly empty when he handed them to me.Sketchy behavior at best and the fact we had to wait even longer while the drinks were properly filled was annoying. For the 15 minutes we waited in the line originally, there was plenty of time to handle the order properly the first time.
