Dunkin' Donuts in Birmingham, Alabama

I usually don't have time, but today I do. I was sent to get two small easy orders. I definitely said I have two orders, first order 2 egg & cheese muffins for 3. With a coupon for a free coffee. As if I didn't say I had two orders the cashier says to pull to the next window, I advise I have another order, a coupon for a $0.99 bagel with cream cheese. (Now I'm asked is that all lol)... that wasn't the bad part of my experience but it got no better. I Just had a ridiculously unprofessional experience at the drivethru window, all over a 2 for 3 where I was charged full price. 2.79 x2 ...When telling the cashier that it was incorrect she was dumbfounded, her manager was interrupting her so she turns around (basically yelling at her superior) and I quote "I'm trying to figure out what she talking bout, here do you want to talk to her!", she hands the receipt, he takes her place, I advised the price isn't right and he simply tells me it was right? He shows me the coffee was removed because it's free I agree and say something still isn't right it's a two for three, he still says it's right? Both walk away from the window? as to not hold up the line, I leave, I call AND I GOT HIM, He at first couldn't find the receipt...goes on to say he can't go back that far, mind you it hadn't been long, he's asking for a ticket number, I give every number off of the receipt, eventually its found, (here we go again about the coffee) I advise, yes we've settled that but I point out the fact 2 for 3 does not equal 5.58, he admitted he doesnt know what happened, did not apologize but did offer, if I can come back he'd comp a sandwich or cash refund of the difference. (Something that is inconvenient) I paid with a co-workers card... and I'm over asking, really over this call, and this establishment, I'm not sure why the card couldn't be refunded but I didn't ask. He didn't offer and bargaining is obviously tiresome for the both of us. In comparison to a Chick-fil-A vs McDonald's experience we are far closer to McDonald's and in this moment McDonald's would be better, faster and more accurate or at least reasonable with the refund process. I can't see a future where me returning, wouldn't lead to the same unfriendly experience so I rather not engage. I was just here for the first time a week ago (that experience was just as subpar)but today, benefit of the doubt, it could have just been too many cooks in the kitchen... they were kind of busy, and it seems as if they all were not at their best so I guess I can't expect the best. Resolution I'm just going to pay for my coworker's food out of my pocket. The refund would have been nice but for where this is located, it isn't worth the gas and I'd be skeptical about free food compensation. I hope it was worth it. They can keep the over charge and find a way to deal with such a low and permanent overall rating... I thought I was overacting but from other reviews, I see now that I'm not... also on second order the bagel was overcooked (cream cheese was gracious tho)... still I wouldn't suggest wasting your money here. Starting you morning here, has a high likelihood of starting your morning unsatisfied. Btw you won't find their phone number on the receipt... thankfully Google did have it. Sorry not sorry, being rude has it consequences and I coming from customer service was as pleasant I could be.
