in my opinion..."balance" is the word. of course a working environment should be flexible and entertaining at the same time since it's an outlet selling toys/anime. hence stress level is lesser. though if this benefit is given, employees should understand themselves by knowing when to play at the right time as well as serve customer without neglecting them. if they can play while serving customer well at the right time, i believe customer can also feel the happening in the store. i personally do not like outlet staff to be as dull with no sense of entertaining customers.
best example is SAM at XL Berjaya Times Square outlet
You have a point there
I agree: Stress is bad for work
and stress and reduce work performance, reduce interest, reduce productivity
Problem is: from what the other brothers relate, these staff are playing too much
