I learned many years ago that Sonic servers worked for tips like waiters do in any other restaurant. So I try not to come here if I don't have cash for their tips.
It's been years since I've been here so my review is only based on today's visit. Three cars were parked when we arrived. Drive-thru was a lot faster than Drive-IN. No issues with speaker/mic. Server was very polite but brought us another car's order at first. They honored 50% off text promo from Sonic. Ordered five Sonic blasts, different flavors. I thought it had more ice cream than a balance of ice-cream and add-in... Snickers, Oreo, Reeses, M&Ms, etc. but everyone enjoyed them and were very pleased.
I'd recommend it to anyone but I would suggest ordering in the Drive-thru line instead.
