I am reliably informed that there is a plan to offer free wifi in the area of Basingtoke town centre in Hampshire (UK), which is going to be used for a variety of clever marketing purposes.
This may be considered to facilitate "showrooming" by Amazon customers at shops in the town centre, directly undermining the tenants of the shops in Basingstoke, many of whom compete with Amazon.

"Showrooming" is the practice of consumers examining products in a traditional bricks and mortar retail store "in the real world", and then buying them online, often at a lower price on Amazon, Ebay etc. This is as an e-commerce site can often offer much lower prices than their high street counterparts because they don't have the same overheads such as prime retail locations.
