If I go to Starbucks and order a medium anything and am "corrected" by the cashier that it's a "grande" I will stare at the offender until they feel uncomfortable.
If I go to Coldstone Creamery and order a medium anything and they aggressively say "oh, you want a 'love it'," I will tell them no, I want a fucking medium. You don't get to tell me how much I might or might not like it in advance.
Also I hate when Dairy Queen insists that you watch them flip the fucking Blizzard upsidedown. I don't want your meager marketing trick. I want the bad ice cream with candy in it.
