I really doubt that the few grams of plastic make a big difference.
Unless you just fly to DebConf because of the cup. ;-)

Not yet.

A rough estimate: 
2 cups per person per day * 300 attendees * 7 days * CHF 0.10 per cup =
420 CHF =~ 336€

So if my estimate is correct it would be a bit cheaper, but not that
much. But if we also need cups for DebCamp, the difference is even
smaller or nonexistent.

I'd prefer the first cup for everyone to be free.

I agree that only the first cup should be free and that replacements
should be paid for.

IMHO we should leave this to the bar team to decide. They should chosse
the way that works best for them.
