When do i get my new computer

I installed a new computer for a customer to replace their 6+ year old desktop. It’s clearly a different computer a full sized tower compared tot he micro they had before and it has Win 10 as opposed to Win7. I get done setting it up (join to domain, have user log in etc) and the user turns to me and asks when she is getting her new computer. I’m like this is your new computer… her comment was then why isnt my screen bigger. Turns out she wanted a new monitor with the pc and they didn’t order one for her.
