This sonic was having a special for HALF PRICED grilled cheese. We went through the drive thru and ordered 3 of them thinking about a $1.50. Well we charged almost $5 for three grilled cheese. And when we said something we were told "we only give out the .50 grilled cheese if you bring it up to us". Which I think is absolutely stupid and terrible service. So you're gonna promote .50 grilled cheese but won't give it out to anyone unless they tell you to? Dumb
