Stinging attitude from WONDERPARK CHICKEN LICKEN CASHIER

I was at chicken licken wonderpark at 19:58 to buy food, There lady who was the cashier that time told me grocery trollies are not allowed. I was alone in the mall and i could not leave thr bag outside as i told her inside my bag there is laptop and some gym stuff unfortunately i cant leave the trolley outside unless she gives me an alternative. She insisted to lift the bag which was heavy, as i said it has laptop, gym cloth and some groceries i did after work. I could not understand cause the shop was empty only 3 people waiting for their orders. What was the fuss about trolley cause it was not taking anyone space. If is how chicken licken wonderpark behaves, not surprised people have shift focus to PEDROS WONDERPARK. I don't understand issue of trolleys only if is packed understandable but empty and refusing me to buy food. I left the restaurant without buying.
