Checkers Drive-In Restaurants Avis 26

This is specifically about the corporate owned restaurant in Port St. Lucie at Gatlin and Savona. Two months ago I ordered a #4 value meal with a diet coke. The meal was $6.89 plus tax as stated on the sign. I was not offered any upsizing. At the window I paid over $8. I knew this was wrong but left. Next time I order the same meal and got the same treatment. I went to the window and got a refund. Third time I was asked if I wanted a medium or large. I said I want what is on the sign. The sign does not have any info about a medium or large and there are no other prices posted. They gave me a large and it cost over $8. I asked the person at the window giving out the food "are you trained to upsize every meal"? The person did not speak but smiled and nodded emphatically "yes". I have done this seven times and the result is the same each time. They may ask you if you want a medium or large but you are never asked if you want what is on the marquee. The price on the marquee is for $6.89. Even when I say I want what is on the marquee, they will up size it. Sooo, if you want your money back you have to park and go to the window. They will apologize and refund your money. So much for it being a fast-food place.
This is not a franchise; it is a corporate office. The employees are being trained by the owners to be deceptive and cheat their customers on a regular basis. I did this seven times because I wanted to be certain that this is not an aberration. I did not want this to be true.
