When others buy me what THEY think I'll need .... I usually go find some hole to bury it in!
Bean counters are worthless when it comes to purchasing stuff for people who work with their hands!
Buy yourself a jug of Big Blu and be done with it. If this causes an arguement, buy a bottle out of your own pocket and just keep your mouth shut.
Those people who bought you that crap would probably NOT be mature enough to hold an intelligent discussion with in the first place. So dont waste your time trying to convince them of what your needs are. Afterall... they never considered you significant enough to warrant ASKING prior to their great discovery.... now did they?
Find out when one of their kids is having a birthday. Not a young kid, but one who is older ... like teenanger or young adult. Then make a point of wraping up a bottle or two of that bubble stuff and sending it to their kid, as a birthday present.
