We were frequent customers of Peter's, getting their family fries with gravy and shakes as a family treat at least once a fortnite. One evening after lining up for 30min we were informed they are out of family fries... Wanting to know more detail, I asked to speak to the manager, who said they are out of containers (not actual fries) so they cannot serve family fries.

It was busy that night so they tried to get rid of me asap, asking the next person in line for their order while I was still there - very disrespectful.

After all the years leaving them business I unfortunately discovered they don't care about your custom or loyalty, money is all they care about. Never went there since...
