Train or fire rude employees. Get them to understand that a long line at their window is NOT a good thing. Teach them that BSing with fellow employees while customers stand in line loses cash. Re-institute QUALITY CONTROL. Make franchises pay penalties for slovenly kept stores, rude employees, poor product quality, etc.
Raise the pay a few more dollars and watch the people applying there change overnight.After taxes making 6.75 an hr just aint gonna do it. They should clean house...fire a good portion of their workforce...and do actual interviews. Not warm bodies. That will be good for starters. Then offer between 9-11 dollars an hour. A lot of these people work their asses off for peanuts.
Bringing back some good slogans and even the characters they have like Hamburgular,Frie Guys, and even Ronald would not hurt either. My son loves that place because of the fries and the characters. I noticed when I was at one the other day the bags and inside had a 1950's appeal to it.
