the ice is extra

I noticed something that bothered me today at Dunkin Donuts. The price of a regular small cup of coffee was $1.19. The price of a regular small cup of iced coffee was $1.39. The only difference is that the latter comes on ice (and as a result less coffee). I don't drink coffee, but I want to go in there and order a hot cup of coffee with ice.

at some time or another i have made the comment (or joked in some fashion) about calling someone for their phone number. without getting too complicated or technical (*69, cell phone entries, speed dial, etc.) the point is that to be talking you would have already dialed the answerer's number. aka there should be no reason to ask for it. well the reason i bring this up is because i was thinking about email signatures, something i have written about before. i noticed that many people include their email address in their email signature and i don't understand why. the only way for a email reader to see this information in your signature is if you successfully transmit an email to that person. and if that happens, don't they already know your email address?
