When you meet or talk to a new prospect, it's natural to trip over yourself trying to make them happy. Maybe you give them extra attention and all that. They don't have a relationship with you or your staff yet, so you want to make the best first impression possible to win them over from the start.
Whatever you do, don't get complacent when serving established or long-term customers. It's an easy thing to do. You're so focused on pleasing the new people, the current ones don't get the attention they deserve.
One of the best ways to keep everybody happy -- including those who've attended your camp for years -- is to pretend you're talking to EVERYONE for the very first time, even if you've talked to them a thousand times before.
Your kindness and enthusiasm will show through, and your customer relationships, long term and short, will continue to grow.
