Citation needed.
See? I can do it, too.
I see you are a bit slow so I will try to break things down into tiny bits so you can understand them:
You made a wide sweeping claim that '
Most people who work at retailers love working holidays.'
Now if you are going to claim that
most of the ~4.5 million retail workers in the US like working holidays you really should have a citation to back up your claim. Sure there are no forum rules that require it but without one there is a reasonable chance you'll get called on it. Thats fine too unless you decide to get all whiny when someone calls you out for making seemingly idiotic sweeping generalizations
My statement was not even remotely close to speaking for 2.25+ million workers let alone a large group of individuals outside of my sample group and specifically stated it was my personal experience so 'citation needed' has no where near the same relevance to my statement as it did to yours. Furthermore you made the original claim so the generally accepted universal convention is that you need to prove your claim.
So congrats on having the intellectual abilities of a parrot as you were able to repeat something you saw\heard but failed to grasp the meaning behind it.
Nearly everyone I know who works retail likes working the holidays because of the extra pay.
We aren't talking about everyone you know. We are talking about your statement of 'Most people who work at retailers love working holidays.' Do you know 2.25 million retail workers? If not then this last statement of your has no bearing on the conversation at hand unless your claim is that the people you know constitute an sample size adequate enough for you to speak for 2.25+ million retail workers.
