No trolleys allowed??

Zara store does not allow trolleys in their stores ?? No policy written on the door! An unpleasant security guard just appears to say no trolleys allowed ..this is the third time I had an unpleasant experience at ZARA..pathetic and poor service..I will not recommend any person to shop there..imagine having a trolleys full of packets and you being told you cannot enter with it nor will they watch your trolley for you ..so are you supose to shop at Zara only if you visiting the mall ????
