Dunkin' Donuts

I visit Dunkin Donuts two to maybe 3 times a week during the morning since i work right infront of it at 39 E. Jackson, Chicago, IL 60604. I have had several misunderstanding with the cashier not taking my order's correctly. They either over-charge me or say that they did not charge me the correct amount, etc. Today, Friday September 24, 2010 i walk in at 7:09am and i happen to order a # 4 on the menu which is a Sausage Egg Cheese Croissant with a medium Coffee. I always upgrade to a large Coffee which is a few cents difference and i always end up paying a balance of $4.93. Instead, the cashier Karla M. rang up a completely different order, which was a Sausage Egg Cheese Wrap and charged me the same amount. I complain her and say this is not what i ordered. She goes to the manager, i don't recall her name, and explains the situation. The manager comes up to me and quote says "The cashier rang you up a different order it will be $1.87 additional for me to exchange you a Sausage Egg Cheese Croissant". WHY do i have to pay more when i always order the same thing and it comes out to the same balance. Funny it isn't the only time they have done this to me and for anyone reading this, they will mix up your order, over-charge you, etc.. I ill not be ordering from that Dunkin Donuts location again.
