My neighborhood fast food pizza joint - I definitely encourage all to use their online rewards program. You will get bombarded with texts and emails but if you will get 1/2 off's, discounted pizzas, and I was able to lock up a free pizza after 2 orders.
On one occasion I selected carry out online and somehow selected BBQ sauce which i strongly advise against since it's so sweet (unless you like it). I didn't notice until i got home but then drove back to see if they could make it. The bbq sauce was so horrible i was willing to just pay for a new pizza. The lady was nice enough and made a new pizza on the spot. i tipped her a few bucks out of appreciation but i really appreciate their customer service which was more than likely my fault when ordering.
