I gave the dude a wtf look and said NOOOOOO I need tubing, silicone tubing not a tube of silicone. All the while my 2 year old was wearing her red and green stocking cap screaming (ok talking loudly) that he was HO HO (aka: Santa). I just dropped my evil stare and said "isn't she cute". But, it got super funny when he got the right size tubing onto the outflow of the filter and the fitting popped off. He thought he had broke it and started to get nervous, lol. I told him not to worry just cut the length I need and price it. He also thought the tubing should fit inside of the fitting. Obviously not the smart one. You want me to send him to your migrant work crew Bill????????? LMAO!
