To be honest, I've never liked the way dealerships/garages treat consumables, especially when your car is being serviced at a fixed price (fault repairs aside). As such, all consumables, whether they be items due for complete replacement (oil, filters, plugs, etc) or those needing topping up or applying selectively (screen washer fluid, lubricating spray), then somehwere along the line certain items in the first group are going to be upped in price if the level of the second group of items is low, just to reach the 'fixed' price.
In that regard, when I have my Mazda3 in for service (the same was said for my old Micra over 10 years ago), I deliberately DO NOT replace the washer fluid, but generally make a mental note of all fluid levels and odometer reading just in case someone at the garage is in the mood to rip me off.
Fortunately this hasn't happened so far, though they (both) have on more than one occasion forgotten to carry out the 'complementary' wash and vac, and one recent occasion (unfortunately I noticed this months later, so too late) when after the wash and vac, the driver's side car mat screw had been removed (presumably when they removed the mat for cleaning and forgot to put it back) and one of the roof line clips had disappeared (probably due to it being pressure washed off by mistake). Unlikely to get any joy come this year's service (parts for an 12yo car like that probably aren't indivdually stored on the premises and are probably only available in a complete set), but you never know!
