Naughty then nice

One day I went to the shop at the corner of my road to get some sweets. When I got there I saw some chewing gum. I felt like buying some, so took a packet to the shopkeeper. he grunted, "Give me the stuff you want to buy". I said, "Ok" & handed him my stuff.

Then he growled, "Give me 50p. After paying, I left the shop.

The next day I got dressed and went to the shop to buy some more chewing gum. I picked up the chewing gum & I went to the same shopkeeper, but this time he smiled "Hello". He was much nicer than before with,"Hello", I replied. "That will be 50p please" he said. Then I said "Sure", the shopkeeper said, Thanks for your business - I said "No problem" "Bye" he replied.
