Was eating dinner at Lau Pa Sat and needed to go to the washroom badly. I entered the hotel and asked to use the washroom, they told me that i had to be a guest to use it. At this point I was very urgent and begged them to allow me to use it . They said no and told me to leave. Take note I was dressed appropriately and I spoke to them in a nice manner.
