If the three times a year pond skaters are too lazy to dry off blades after skating, no way they will do that. I was going to say, that would require customers doing something useful to protect their equipment. Honestly no matter what kind of condition the blades are in, I still take it personally when someone hands me a wet pair of skates. Ahmen to that brother. It don't take a whole lot to dry your damn blades as a courtesy to the sharpener. I just feel like throwing the skates back at the customer, but of course that will never happen.
