Service was quick but utensilsv and napkins were not set at table, so we had to wait few minutes after waving my hand to let them know…
So far , food was good, nice atmosphere, good deals for seniors
I couldn’t understand this behavior. This is a business, and basic courtesy should be shown to customers. Encountering such indifference and rude attitude was truly upsetting. This kind of behavior damages the image of your business and seriously affects customer satisfaction.
I wanted to bring this situation to your attention and kindly request that appropriate action be taken.
( Except Omar, because he finally showed up. He humbly gave me the order. Sorry about the wait.)
However, anyone using the app for discounts, should double check the calculation for discount. To start, you can see my receipt from the picture below. I was expecting around 4 dollars off with the 20 percent applied. In the app, it states 20 percent off you entire order, it does not describe any sort of restrictions to this even when you click view details.
For example, the person at the register told me that the super slam does not count towards the 20 percent because it is already so cheap. So already, I was a bit caught off guard because there was no fine print on the app about this.
So given the receipt below, not including the super slam, before tax 3.99+2.19+1.99+1.99+1.99=12.15
12.15 x (20%) = 2.43
But I was given a discount of $2.39. I know it is just a few cents, but as an aspiring accountant I would love to know the process behind this calculation I have already sent feedback to corporate about this. I don’t blame this location in particular, but the fact is this seems like a misrepresentation on the corporate side.
With around 1300 locations nationally, let’s say and average of 10 coupons like the one I used today are redeemed at every location, and taking into consideration my 4 cent deficit….
1300 x .04= 52 x 10 coupons = $520 x 365 days = $189,800 of discount promised but not given.
Maybe I am crazy and have too much time on my hands. I welcome someone to tell me differently and that I am wrong, but if something like this could be proved…Denny’s I think you potentially have a problem on your hands…
Food was great service was even better. We will definitely be back.
