Well, who knows. Maybe there?s a washer fluid shortage and the barely out of high school kids that work the lube rack were advised by management to just top things off with water.
Plus, let?s not forget that the average temperatures in December were what? Fifty degrees? Maybe they thought it wasn?t a big deal and that I?d probably use it all up before it got cold enough to be an issue.
Most likely its just a general lack of common sense or life experience. Looking at them I would say the kids working in the lube section where I had the truck serviced were all probably between the ages of eighteen and twenty-one and they?re probably paid peanuts.
No harm, no foul since no damage was done I suppose. Also a life lesson for me. If I take a vehicle in for service in the winter months I should just make sure I bring it in with a full washer tank so they can?t add water.
