I guess a tough customer I had one time was this elderly gentleman who would come in to the cafe every single morning and he would order like a garlic bagel with butter on it and the way that we did it was kind of like Bialy's, the roasted garlic was just right on top of the bagel and he had gotten upset about the way that the kitchen had prepared it that morning and I hadn't personally done it so I couldn't explain to him what had happened but instead I told him I'm so sorry this happened, please go sit back down and I will personally go make you another bagel and come out and make sure that it's to your liking and I didn't have to, I didn't charge him for another one or anything and he was happy, I was happy, it was a stressful situation because he was very upset in the beginning but at least, at least we got through it.
