I think we can all relate to how Basil is feeling here - tradesmen can drive you to despair (nevermind that I can never look at Garden Gnomes the same way again).
From: The Builders (the second episode of the first series, broadcast 26 September, 1975)
Basil: (back on the phone) Now look here, O'Reilly. I want my dining-room door put back in and the other one taken out by one o'clock, you understand? ... No, no, I don't want a debate about it. If you're not here in twenty minutes with my door, I shall come over and insert a large garden gnome in you. Good day.
And now a few wise words from O'Reilly himself...
O'Reilly: Well, let me tell you, if the Lord had meant us to worry he would have given us things to worry about.
Basil: He has! My wife! She will be back here in four hours and she can kill a man at ten paces with one blow of her tongue. How am I supposed not to worry?
O'Reilly: (calmly) Just remember Mr Fawlty, there's always somebody worse off than yourself.
Basil: Is there? Well I'd like to meet him. I could do with a laugh.
O'Reilly: You'll have to worry for the both of us. I tell you, if the Good Lord...
Basil: Is mentioned once more, I shall move you closer to him. Now, please...
