Others involved with production of some type, even if it's not the same type going on, tend to be more amiable to changes and going with the flow. I rarely find that to be the case with the average end consumer and I certainly wouldn't assume so to be comfortable enough to do it without making sure that it's in writing that they were aware of changes and if they wanted to do them (typically I mean by email).
As to the above situation, given that there was just "tape" mentioned and nothing else, a call/email (whatever is on record for preferred contact) to see which one is needed, not to be assumed that it's one, even despite the historical record of having ordered that. If they wanted to mention "you always buy 'x', but I see here that you have 'y', is that correct", that's another way to give that nice touch that the are looking back at the records, but still aren't assuming. Now depending on how one orders and there is a default to a size or whatever makes one different from the other, that's another wrinkle in the situation.
See, I wouldn't expect that, not necessarily with my buying "x", but now bought "y". Even after years of buying "x". Now, if they want to call/email to make sure, that's a nice touch, but I wouldn't expect that to happen. Rather or not that should be expected, that may be up for discussion. I guess another reason why I don't expect it to happen is even with vendors that I have over 20 yrs experience ordering from, have never done that.
I was just going over the analogy that was presented.
Have fun when you get the customer that comes from the designer that says that there should be no reason why the production person is unable to do what they need to do with the file "as is", even though they may not be aware of all of what the customer is going to be doing with that file, let alone know what is needed to know for quality production. That to me, takes incompetence to a whole new level.
