100%. I think a fielded a version of every one of these when I was a kid. My favorite is the unanswerable statement... These days it's "It said on the website that it was in the store"... as if A) it couldn't have sold out between now and then, B) no errors ever occur, or C) the staff is hiding it from you?
I like the video and agree with these A, B, C, reasons but I am glad for the web inventory note and don't feel bad asking because I have experienced numerous times where the stores did have it but it was (a) dual located on an endcap or special display, as well as the normal aisle spot, or (b) they did "find some in the back", even though I am aware stores have less of a backroom now with a "truck" that comes a couple times a week.
"A" can happen but usually it means the computer inventory is correct - "it is here somewhere", and staff has educated guesses about the somewhere, where before you would just give up.
