There's certainly nothing wrong with what you did.
In my case, I'm a regular customer and I make an appointment a day or two ahead so when I go in, I don't have to wait for them to get to it.
Since I know everyone at the shop, the oil/filter change is probably finished before I make my rounds BSing.
FWIW, I still do my own oil changes on my old Nighthawk. Just pull the plug, let the oil drain,replace the plug. change the filter, fill it with oil. Naked UJMs are easy.
