Engen Langverwacht Convenience, Kuils River

Hi there, i live approximately 5 minutes away from your convenience store. I work from home and i work odd hours/shifts. Often i pop into the store after work, anytime from 2am to 6am in the morning depending on my shifts to grap a few items. I do not spend any more than 5 minutes in store as i already know where everything is packed. The ladies on duty (not all the ladies, some are nice) at these times always make me feel like an inconvenience or that i am somehow interrupting them, making comments about me in there native language. It makes me feel very uncomfortable and i was hoping that someone could kindly address this matter, thank you
