I assume you are referring to the mathmatician. It's odd because reading what you said makes me think I'd rather a diversity of product types, but I care less about having more than one of each type. Having said that, Tesco stock a Jamaican stout (Dragon), and for about a year, they didn't stock it. And it intrinsically annoyed me. They did replace with a like product after a while (Guiness version), but I didn't like that.

Which makes me aware that you can get fussy over different brands/tastes. Beer is a good example actually.

There was something that really bugged me about being offered the product and then having it withdrawn, it's replacement wasn't enough.
