Customer the other day:
Her - I need product A. I bought one a couple years ago here
Me - sure, they're right over here. (Walks customer to display) I have these three models, X, Y, Z.
Her - no, I want model 1
Me - I'm sorry, they don't make model 1 anymore. They made updates to the product over the last year so now they only have X, Y and Z
Her - I want model 1.
Me - yes ma'am, I understand you preferred the original model 1, but unfortunately the company no longer makes model 1. It was discontinued over a year ago and now they only offer models X, Y and Z. They offer additional features the company thought people would like
Her - can you order me model 1? Go check your computer for me
Me - (starting to hate our "don't tell customers no"policy and gritting my teeth). Sure - my computer is over here, I'll see what we have. (Looks up the item). Right now we only have models X, Y or Z available to order. It shows here in my inventory system that model 1 is in "discontinued" status. It's not available anymore
Her - when will you get more in?
Me - (when pigs fly...). I'm not sure ma'am.
