In the Absence of Logic

So we got a refrigerator last year and one of our requirements for replacing it was we wanted to make sure it had a filtered water dispenser. I replaced the filter last time by going in to the dealership where we bought it and the salesman just grabbed one for me. This time I decided it would be different. I googled the model of the fridge wanting to find the type of filter I needed and see if I could find it somewhere cheaper. After pouring through whirlpool’s site I couldn’t find anything describing the make of filter I needed. I did find where you could order one by saying, “That’s my fridge, send me a filter”, but it was even more expensive. So I gave in and figured if I went to the dealership one more time I’d save the box and go from there in another six months. So, again, I wrote down the model number and went in to the dealership, but this time the salesman wasn’t sure what type of filter it took. He asked me if it was a “push in” or a “turn” and I really couldn’t remember. A couple times I offered him the card with the number on it, but he said that wouldn’t help. Finally he gave up on my memory and googled the model number I had with me, but to my surprise he didn’t look at any of the fridge info, he opened the picture of the fridge and squinted at the bottom of the photo where the filter goes. He then dragged me to a floor model and asked if the “…cover plate lookes like this”, pointing at the corner of the fridge. I said that I thought so, and he grabbed me a filter, which of course, worked. But wouldn’t it be simpler to just say, this fridge needs a type ‘X’ filter, right on the fridge?
