One particular instance I had of a difficult customer was at the time when I was a barista, and we had mostly, most of our customers were regulars, and so we'd see them on an almost daily basis. One particular customer had a very particular drink that she liked, and very specific ways she wanted to make it, exact measurements, and she only wanted one barista to make it. Well, one day she came in and that barista wasn't there, but luckily that barista had trained me on how to make her drink and make it just right, so that way if she ever did come in, and I was the only one, that I could make it for her. So she came in, and she was obviously not happy that this barista wasn't there to make her drink, and wasn't happy that I was going to be the one making it, but I told her, I promise you, so-and-so told me how to make your drink, so I'm going to do my very best to make it how you want it to be. So I went, and I went, and I first described to her what her exact drink was, that I remember the other barista telling me, it has, you know, this many pumps of this syrup, and you make it this way, and this is how you like it. So I went, and I very carefully made it according to the instructions and served it to this customer, and she was immediately just so happy and tasted it, and that it was just right and exactly how she'd asked for, and was surprised that I was able to follow through and make it exactly to her particular requirements. And so that was how I ended up befriending this customer, and she was always happy to see me afterwards and trusted me as well from there on out to be able to make her special drink for her.
