I am writing this post at a small cafe while my car is being serviced. I tried a local Red Rooster food store, a KFC, and a McDonalds but none of them had a power socket I could use. This seems quite perverse as McDonalds advertises free wifi net access to entice customers, but no power to charge laptops, phones, etc. So anyone who has 3G net access will avoid that particular McDonalds store in spite of the free Wifi.
Also this is not something that happens accidentally. Power sockets are needed to power the variety of cleaning equipment that is used at fast food stores and it would same some cleaning time if they were centrally located, so someone at those fast food stores apparently decided to put power sockets out of reach of customers. I’m currently seated in a position that is within vacuum cleaner range of every table in the cafe, so whoever rents the premises to the small restaurants has thought of these things.
At home tariffs a laptop will consume about 1/3 of a cent worth of electricity per hour. It seems to me that a smart business owner would want to have several power sockets available to customers and advertise this fact. One cafe has made considerably more than 1/3 of a cent profit from me due to having a power socket where I could use it.
Note that not all McDonalds stores have this problem. One I visited last week had a power socket where I could use it. I noticed that they had made a good choice of uncomfortable chairs to discourage customers from spending too long there, it took the rest of the day to recover from a couple of hours sitting in McDonalds.
