I'm a chronic worrier and I too enjoy time when what's going on at the carwash is not in the back of my mind.
I close my SS bays on certain holidays. This year the rain started about 1 pm Christmas Eve. I shut the bays down and left the autos open. It's really nice to not have to worry about things.
A local operator closes one of his washes down at around 6-7 pm every evening. He claims the customers have adjusted to it and the numbers have not gone down. He does have the market to himself. At his other washes he closes the SS bays down at night during hunting season. I'm sure he loses some business, but he pays cleanup labor and doesn't think he's losing anything. Regardless of the bottom line,he'd rather not deal with the mess.
Nothing wrong w/shutting down sometimes.
I've been tempted to do something drastic after a long period of rain for these same reasons, but I can't think of anything that would work. I'll spend two days shoveling mud and pressure-washing the entire lot over and over for a few people who spend a couple bucks to knock off mud. The worst was when someone shut down the last two clean bays AND the auto with one muddy truck, spent less than $10 to do it. I'm thinking about putting up signs stating that a $200 fee is required for "recreational mudders," since that's where most of the mud comes from.
I can see the point of '24/7' in some markets. For me it's about economics. It doesn't make sense to be open all night and heat the floor slab when it's 0F degrees and I'll take in $5. Am I really alienating customers who expect a 24/7 operation 365 days/year?
Bottom line is I am in business to turn a profit and during Winter months in New England, there are plenty of hours in the day for customers to wash in the daylight when tepms permit washing w/out icing the car all up.
Of course that is a matter of opinion and everyone can run their business to suit themselves. Me, I never close. I'll take what the "sissy"operators leave on the table for me. Seriously though, I don't want a customer to come in to wash their car and find the place closed when it's always been a 24/7 business. If that happens to the same customer more than once he is going to have the impression that "Wiz Wash" car wash is always closed and find someplace else to wash from then on. I know very few things get under my skin more than seeing one of those "Be back at whatever time" paper clocks when the place is supposed to be open. I don't wait for them, I just go someplace else.
I' live less than one mile from my only wash so it's not a big deal to me to alter my operating hours. As far as inconvenience for the customers, this is a bedroom community and even the McDonalds closes at 10pm. I have found of pattern of real messes during hunting season about two hours after dark on Sunday nights. So about 8 pm on Sundays if it's been real wet I'll shut down. As I was doing that the other night a guy drove up with what I think were four wheelers on a trailer. I'm not sure they were four wheelers because all I saw were just two giant blobs of mud. I sent him to Pat's wash.
If I were to ever be in that situation, have cones out, signs out, etc.. I would probably not cover the coin slot and let the person who didn't see the signs or cones stick their quarters in the slot! jking
