Customer appreciation day but when when I tried to order the deals the girl in the drive thru had no idea what I was talking about even though they are advertising it on the widow and pasted out flyers .....she told me she has no promo button for the offer. When I asked so what does that mean she told me she wasn't a manager and couldn't give it to me.... was there no manager on duty???? very disappointed in being treated this way especially on customer Appreciation Day!
