McDonald's

I normally don't have much of a problem with this franchise, but today I, and another stranger I overheard, have had some sort of issue with the staff here. The fellow who I overheard didn't get the right sandwich, I myself, was shorted 70 cents. Not necessarily a big deal, but the cashier hesitated to give me my 45.70 back in change. I saw on the ticket that was my change, but she proceeded to give me just the 45. This is infuriating for one reason. The simple principle that your too lazy to do your job. They lost business from me because the manager doesn't understand she needs to manage, more than service.
