Yes that was one of the things that a customer who took it upon them selves to "preach" to me during my job, while I was stuck helping cut his keys and find the other random items that he said he needed help finding. Strangely this is not the first time I have attracted the type that decided to do some preaching to me to help "being me to Christ" while I'm on the job and their captive audience stuck helping do something for them, how ever this was one of the first times that I really had to bite my tongue to avoid saying or doing something that I would regret and that could get me in trouble with my bosses.
My personal blog, that provides a uniquely North West view on the world around me, so sit back and enjoy.
