I never order soft drinks at Sonic or any other place, bad for you. Seriously, my son worked for a major supplier selling soft drink dispensers and supplies to places like Sonic in OK. City for about a year and a half, said the cost to the vendor for a large drink averaged 7 cents, looks like they could really cut down on the ice.
Reminds me of the time I ordered a Blue Coconut slush in the 100 degree heat and took a big drink. When it hit me I lost all function of my body damn near. Had to pull over and park the truck. That was one of the worst pains Ive ever experienced!
No ice, the carbonated water coming out of the tank is cold enough. Sonic drinks are a rippoff since you can get the same sizes cheaper at a gas station next door. But they're the best at mixing. Vanilla coke no ice for me!!
