Poor attitude

I was at the burger king on racecourse road today. Placed an order at the first window...then after a 15 minute wait at the pick up window and Hearing laughter in the background of the place..I got out of my vehicle, and opened the window (which was still partially closed) and asked if anyone was serving this window...the reply I got was a sarcastic "it's coming sir". I then waited a further 6 mins for just my cooldrink to arrive (come on man) which was right at the window I was parked at??? So in total, 20+mins for a drive through order...no apologies for the delay at all. I then asked for the managers name of the burger king...the lady said it was Arthur, I then asked for her name as well, she refused, and rather went to the back to go and call Arthur...when she came back, a second lady appeared who was clearly not Arthur as he was not in apparently...but she mentioned his surname is Abrahams...

Dear Arthur.

Please train your staff on the basics of customer service...serving good food is one thing, but poor customer service and zero empathy/acknowledgement for the delay, throws that all out of the window...

Seriously disappointed customer.
