I think it is not a bad idea. The shop might have ads or something to help fund the faucet. There might be a timer (5 min for example) for controlling the claims (only one claim every 5 mins). People might wait in queue just to claim Bitcoin!. Other people would see the queue outside and be curious, so more people get to know Bitcoin.
As other fellow poster said, there are some things to take care off, but idea seems good to me.
nice updation on the topic , it is very nice idea , but for donation he has to make advertisement like what all faucets are earning through advertisement revenue and giving free sathosi.
You can get a domain name, web hosting, and faucet script free. The ability to do so makes running a faucet fairly simple, cheap (free) and leads to sustainability and perhaps even some profitability.
I'm not sure the same can be said for a physical Bitcoin "giveaway" shop. The overhead costs of building and implementing the camera systems, microphones, etc coupled with the capital expenditures of purchasing a building and perpetual taxes, insurances and or rent don't lend themselves to a Bitcoin faucet project that even sounds remotely sustainable or profitable enough to justify the efforts.
what you are telling is also correct , but faucet idea became too old. i think this idea is also cool of setting up a shop for earning free bitcoins.
