The delay in the pick up orders was unacceptable. I had an order promised at 12pm but it was ready 30 minutes later. Not only did they fail to tell the long line of customers waiting outside what the situation was (shortage in staff) but they also were unapologetic and rude to any customer that came in to inquire about their orders. Maybe they should stop accepting orders at a particular time slot if they can not commit to it?
