I'm a dealer, and I like kids. I like families. Any exercise that strengthens them is a good thing. I think looking at tractors as a family is a great, even if it is just a "field trip". If people bring in their kids it just brightens our day. They are welcome to sit on the tractors. We make sure the loaders are down and the keys are removed. Sometimes we have to go turn off the 4 way flashers and make sure the throttles are pushed back down after they leave. We can do that! We have several hundred tractors in stock, and we are in California. We are aware of liability issues, and it is true that some caution must be taken. But it is also true that some risks are worth it.
If a kid has not been raised well or is just a handful for some reason and wants to chuck rocks at our cab tractors, that is a problem and we carefully address it. But we see maybe one wild-child for every 25 well behaved kids. Tractor folks tend to work the land and they seem to raise their kids well. It's a nice community. I'd much prefer they bring the kids than leave them home playing video games or whatever.
So Ultrarunner, come on up and bring kids.
So how would you handle it if you weren't at your dealership? What if all of your sales people and yourself, assuming you have more than yourself, were out of the office for some reason and the only person left was an accountant who knew nothing about tractors? Exactly how would you deal with that kid chucking rocks? I can't see a good way to deal with it.
After driving an hour to get it, 15 minutes to load it, another hour back, another 15 minutes to unload it, an hour to figure out that the fuel isn't flowing because someone's kid decided that a great place for his gun was in the fuel tank, and now you still have 2 1/2 hours tied up returning it back to your customer.
It seems like a popular activity for adults to sit around and kvetch about how terrible kids are these days. It's never okay to prohibit a whole class of people because of the bad actions of an extreme minority.
Thinking the police and parts of the government do this all the time.
As I said stop over at Etiquette **** and spend a few days reading about how ugly, stupid, horrid, and insane children and their parents can be.
