Proper Training on Staff

On the 19th Wednesday we went to horizon view to buy some drinks at checkers but we decided to go at Party City at check wat do they have there.. the was 3 ladies and 1 guy.. this ladies they were so friendly I decided to buy something it cost 15 but that guy said he can't help I must buy with more than 50.. I worked at retail I know he was pushing sales but he was not supposed to day coz at retail normally they work with conversion.. each and every customer that enter the store must buy something it doesn't mean that they have to return u when u have to pay..That guy need a proper training coz now the company loose that 15 and it will be added on something..
