Why advertise something that's not there.

The Birch acres mall McDonald's says they've been out of their currently advertised as new peanut buttercup milkshake for seven months. I get that people are tired and they want to go home but I doesn't give your(McDonald's) the right to lie to my face overs something I buy every other day at other branches, classic display of poor customer service. Just because your business is in the local area doesn't mean your service should lack the substance of how you advertise your business. McDonald's used to be a happy restaurant until now.
