I love my Mosque accounts.
I started with one 4 years ago, and now have 5.
The ones I service are not so much what many would consider a traditional Mosque, but more like community centers that center around the Islamic faith, so naturally they require large open carpeted areas for daily (5X a day) prayers.
They take their carpet and rug hygiene very seriously, so they don't require frequent service, but like clockwork, they all get serviced right before Ramadan, and I look forward to the nice income boost during that time.
I am not ignorant to the fact that they don't want shoes on the carpet for several reasons, including that they bury their face in them 5x a day, which makes perfect sense to me, so I have always taken my shoes off during estimates without being asked, and consider it a no-brainer, as this simple courtesy may have very well landed me the accounts.
I see no logic in anyone letting their religious intolerances get between them and their wallet, but to each their own.
I'm in business to make money, and lots of it, and have no shame when it comes down to it, so I'll strap on a pink bunny outfit to clean if your paying the right price.
