Me: *goes to store to get printer ink* excuse me I would like to buy some ink.

Employee: Sure. What printer do you have?

Me: ..............................................................

Employee: You don't know do ya.

Me: *nods* but I have my laptop with me.

Employee: that'll work.

Me: *opens laptop and goes to devices and printers section* here is the  printer.

Employee: Ooh sorry but we don't carry that ink.

Me: But I bought my printer here.

Employee: Well we don't carry it.

Me: Fine. *walks away*

The very store I got my printer doesn't sell the ink for said printer
