‘One cup of hot tea’ my dad told us this when we first started in business. This one sentence, once implemented, made us millions of pounds.

When my dad was in India in the 1930/40’s, the shopkeepers used to invite people into their shop and then ask if they would like a cup of tea. He said that the process was very, very simple, the tea was a free gift; the hotter the better, it meant the longer it would take to drink, the more time to wander around the shop. The longer you would be there, and the more the shopkeeper would befriend you so everything being equal, if there was something that you wanted, why not buy it from there?
Although my dad told me this on day one of opening our first shop it took something like 5 years for us to implement the strategy, and only when we got our third shop!
The more we gave, the more we received, a win-win situation.
