I doubt that it is a problem everywhere, but I just stopped into a Dairy Queen on I10, about 1 hour east of Tucson, Arizona, and found that the price charged was higher than the price advertised. The person working the counter (with an 'Assistant Manager' nametag), was difficult to convince that there was a problem until finally she rang up 1 Large shake, which came up as $3.99 before tax. The sign clearly said that a large shake was $3.49 (not including tax).
When she was finally convinced that there was a discrepancy, the 'Assistant Manager' said she was 'unable to give me the advertised price because the computer would not let her'. Sounds like an illegal business practice to me, but perhaps computers now trump the law.
Like I said, probably not a common problem, but I suggest that if you stop at Dairy Queen, you get a receipt, and compare it to the prices you thought you were paying...
