Attitude issues from your driver

Downloaded the app to order food for delivery from Steers New Market @ 19:55. Phoned them after 21:00 no answer at all. Got through to someone else and she stated that she has been trying to get hold of them for the past 30 min. I understand it was a Friday and you were busy, but what got me angry was the fact that the driver was so arrogant. I specified he needed to hoot 3 times, he delivers @ 22:20 hooting like a hooligan in front of complex, then says we didn't order the milkshake, which he did not bring, double checked receipt, shows on there. He then says arrogantly must he now go back and fetch it cause they did not give it to him. He says this will take another 45 minutes to 2 hours. For a Milkshake!!! Then he has the audacity to say can he take it for himself??? Is this the type of people you want to interact with your clients? Yes, it was only 60 bucks wasted on milkshake and the driver tip, but your driver has a terrible attitude and needs some training on how to deal with your clients.
