O2

Staff are very polite and welcoming. They even offered us food and drink while we were in the queue.
Will remain an O2 customer!

The 02 store I think is the quirkiest phone store around, the design of their store always seems to change at one point they had these blue lights across the whole windows. When I went in there recently they had patches of fake grass around that store which makes a nice change from your standard phone store. What I also like about this store is the fact that when you walk in you do not instantly get badgered and constantly asked by sales assistants can I help you a million times over, I really hate it when the sales men do this, so because of this reason this is by far the best store for that reason alone. You can buy phones from here for £20 up to the apple iphone, contract phones and pay as you go phones.
