A good example of how social media can make it convenient for the customer is CoffeeGroundz Café, a Houston coffee shop.

CoffeeGroundz offers free Wi-Fi, plenty of outlets, and they serve beer and wine – making it a cross between a Coffee House and a Lounge.

Customers sitting in CoffeeGroundz can order food and drinks from their tables using Twitter, without going to the counter. Busy drivers can even place “to go” orders from the car on Twitter.
