Here's The Slice's proposed code of conduct for Spokane area Christmas tree lots.
1. No arguing in front of the kids.
2. No Shirt, No Shoes, No Service.
3. Keep the bargaining cheerful.
4. Sniffing is free.
5. No cell phones.
(Sort of makes me laugh now to think that 13 years ago I thought No. 5 was even remotely realistic.)
