Disappointment of note

Tonight we went to the drive through at the Shell garage in Westridge. The line went quite quick just to get to the pay point and they ask us to wait for 6 minutes,which we don't mind to do. 20 minutes later my partner goes in and she sees that they assisting order numbers in the 300's and our number 649. We left to do an errand and came back 15 minutes later. She went into the store to wait another 45 minutes. When we got home our order was wrong,we couldn't go back to the store as I needed to eat as my sugar levels was dropping as I am pregnant with twins and needed to eat. We ordered a double crunch meal and box master meal but it was just a dry colonel burger and a wrap with a hash brown,no sauce or garnish. The chips tasted it was made yesterday. They never informed the clients that the food would be a delayed. While my partner was in the store,there was lots of customers returning their orders as it was wrong. This was a major disappointment from such a huge food franchise. If the food is delayed say so not tell the people it will be ready in 6 minutes when it won't,don't create an expectation if you can't deliver.
