I was recently at McDonald's in Media P.A the one outside Granite Run Mall, Well my first encounter was with a young lady with micros in her hair I told her I asked for no mayo on my burger but she still asked for my receipt I obliged her and she went off on me I asked to speak to a manager snd she brought a older lady put that said dhe was a gm I told her what was going on snd sje yellef at me also........ I will nevet go there again these people do not weat badges I tried to get the Corp # but layer found out it a self owned store. To this date I still can not get in contact with the owner... Never will I go to that store again!
