Sponsering a teacher near you

My sister is a middle school teacher in a Dallas area school district. As with any government endeavor, silliness is sure to creep in, to wit:

"Our district has a contract with Coca Cola. Only Coke products in machines, etc. They (not sure if it's Coke or [the district]) have decided if we as teachers bring a drink from home that is not a Coke product (like my Ozarka water I take every day) we should put it in a cup or COVER THE LABEL like on TV."

You have to figure this is unenforceable and will thus be ignored, but it does bring up some interesting possibilities, not the least of which is that teachers will soon be wearing uniforms that look something like this.
