Any other regulars notice a lack of Christmas tips this year?

On my old route I used to get a couple hundred bucks or so each Christmas but on this new route I'm on I've gotten nothing except a box of chocolates from one customer.

I mean, I don't expect anything but it's a little discouraging. I feel like I'm doing a good job providing the best service I can. I don't misdeliver. I hear about other coworkers getting upwards of a thousand dollars in tips and I get nothing. I guess it is what it is.
