making excuses

My husband is a handy man so every time we have problem here in our house he fixed them when he can. So I really have no worries about home problems because he takes care most of it, but sometimes I have to wait longer for the job to be done. He always has excuses and it makes me mad. Last time our kitchen faucet was having a problem I asked him to fix it and he said I need to buy a  titeflex teflon hose first. Every time he has to fix something, he always has to buy things and it makes me mad. I feel like he only do it to make excuses.
