Hardware

How hard can it be to join a plastic pipe ? Twice ive been to a hardware store who have given me 20mm connectors for a apparently 20 mm pipe . Niether sealed it . When i asked why a young man said well these are 20mm ones and looked blankly at me . Know it was obvious that they fit wrong , but why ? He made no effort to advance the situation and was totaly lost . He could only see what the packet said so it must be alright ! You stupid c**** i thought . Typical next generatiion . Probaly never fixed a thing in his life ! Clueless . Am i getting old here ??? You can smell the fear in that store . Nervous tension as no one knows what there fucking doing . Earlier on in the week i ordered roofing material . EVERYTHING THAT WAS DELIVERED WAS WRONG . Christ cant any one get anything right !!!!!!! Very tired and pissed off tonight .
