Tell him to pay half or to go do one, his assumption that you were just going to hand it over doesn't sit right especially when it's someone you've barely spoken to for ages (would be more agreeable with it, if he was your best mate who you hand out with every week and who buys you pints in the pub etc. and you offered first) If you do without even broaching the subject of paying half for access, then what will he be expecting from you next? If he's rich enough to smoke everyday, he's rich enough to pay for half your broadband, or for his own internet. There's no such thing as a free lunch.
