Why, one wonders? Why would a Sonic have bad reviews?
Well I ordered a small vanilla milkshake $2.99 for my daughter, was charged $3.39 for an oreo milkshake. Informed the gal, it was not vanilla. She took it back, brought a vanilla one.
It's bad enough that this business charges for ice water, now 40 cent overcharge for an incorrect item. It might seem trivial but if even 1 out of 50 customers is over charged, they are raking in serious money. Will have to find another milkshake spot.
