WHERE CAN I GET POPCORN? PLEASE.

I am currently staying in Hanoi Buffalo Hostel in Old Quarter area. I have some microwavable popcorn packs with me. Yesterday, I asked the reception if it is possible for them to microwave the popcorn for me. They said yes. Came today, I went to the kitchen staff and they said it's not allowed. I mentioned that it has been communicated to the reception yesterday but they just apologized.

Anybody knows where I can have a plain/salty popcorn, or where I can rent a microwave? My cravings is killing me. I am on my first day of period.

I already went around the convenience stores and they don't have popcorn. Please help. 😭
