Worst service

Worst service ever!! Went to greenstone, asked for straight forward zero cut on back and sides and blend in with the top. Ten minutes later “barber” still containing to chop and change between numbers with no clue how to blend. After again explaining I get told he knows what he is doing! I know what I wanted - how dare he decide for me how he wants to cut my hair. After paying the ridiculous amount of money for a half cut and bad service we get told to get out!
