I personally think you got RAPED if all they did was the 4K or 1 month service stop in your owners manual. That is a oil change W/filter for the most part. Sure wish you lived closer to me I would do it for ya for $25.00 and a case of Miller Lite !
If you had your bike serviced in your home town. then everyone there is glad you did. The Honda shop made some money, the tech made some money. (they will spend it in your town). The County made some tax money.
It was a fair price and you keep the local town running.
I do this type service for .75 hour labor (22.50) plus cost of honda filter (8.50) and cost of oil...whatever brand you prefer...check bike over for bolt looseness, side cover grommets, coolant level, add if necessary and change Diff. oil...you wait on bike if you please, cold drink, coffee, or water...dealer around here cost much more, leave your bike there a week or so, if you are lucky...and yes I stay very busy...harley and metric bikes...PS...Harley service is just a bit more, but very affordable compared to local harley shop...
