I went to a different sonic today and the service was great.
Not related to rude people but I saw a sign by the sink and it was talking about how to make ice cream slushes. We asked her if they had them and she hesitated for a bit and said yes. I haven’t seen them on their website or nutrition page since last summer. I wonder if their bringing them back and just haven’t formerly announced it or if it’s some secret menu option. I plan on going back to my local one on Friday and ordering one. Although I’m sure I’ll probably get the run around there.
