Thanks for the feedback! I was actually flying in from Singapore, transiting in Hong Kong (13 hour flight) so there was no way I could have informed you prior to arriving since my flight left on time. I did try to get in contact with you ASAP when I landed, but it was also unfortunate that my luggage was further delayed. Nonetheless, I do apologise for making you wait since it was a Friday evening and I'm sure you had other plans.
As for the trash, we sorted it into a bag of recyclables and 2 bags of non recyclables (but it might have all been mistaken as trash), but lack of emptying the rubbish bins in the room and the bathroom as well. We're sorry if we had missed out anything, and thanks for taking out the trash on our behalf! :)
