Just bought a coffee and a green juice from this store, went to use the bathroom, 2 seconds after I went in the bathroom someone started knocking on the door aggressively, apparently that was the security guy knocking. I went out of the bathroom 2 min later and he said I can t go before he search my camera bag and myself. Although I was holding my 2 items in my hands and I had receipt for everything. Felt really embarrassed getting searched in the middle of the store in front of hundreds of customers . ;(
