When you take a short cut

So, preparing for trip away, decide to pump up tyres on car. Doing the last wheel and I dropped the rubber cap into the hole in the hub cap. I could have gone and got a tool, but no, I decided to use my ignition key rather than get my hands even dirtier. Lucky I have (had) a spare, but now with two days to go I think I need another one cut. Idiot boy. Not much call in Timpsons for 1970s keys.
