> For instance, one customer has 15(!) cronjobs.

But they didn't ask US for help. We didn't need to know a customer of yours is running 15 cronjobs. Even if this factoid itself may be harmless, it's a good thing to practice on how you talk about these things. I'm not saying you're doing anything wrong, I don't know that, but I totally get why how you talk about it rubs some people (including me) the wrong way.

> Its not an engineering company, the owner has a sales background.

Again, it's good if you have a close relationship with your customers, but we don't, and they don't have one with us.
