Eating and drinking while moving is generally frowned upon in Taiwan. Similarly, if you are a smoker, it is proper etiquette to stop and take a break to smoke rather than walking while smoking. Eating on public transportation is also widely prohibited, with the exception of long-haul trips where boxed lunches (便當 Biàn dang) are commonly sold before trips. 

Taiwan has very few public trash receptacles, especially in public walking areas that are managed by the city. It is expected that you will carry your trash with you until you are able to find a place to throw it away.  Convenience Stores (便利店 biàn lì diàn), the Metro, and train stations are good places to throw away any waste collected. If you find public waste disposal, they are often broken down into various categories. These are to separate recycling, please make sure you are sorting your trash properly when throwing it away. Not all bathrooms will have bathroom tissue, so many carry a small pack with them in their pocket or handbag. You can find them in most convenience stores.

Squat toilets are still common in Taiwan, especially when venturing to older areas like Beitou or outside of major tourist areas.

Taiwan does not have a large tipping culture. In fact, if you try to tip in a restaurant, you will most likely be chased down by the service staff to let you know you left change. Not only does it lead to confusion, but some may find it insulting as  it makes employers feel you think they are not being paid enough and makes employees feel like you think they need handouts. There are a few times when tipping is acceptable, but most of the time it’s better to not tip.
