Vietnamese vocabulary book

When traveling in Vietnam:

When you want to choose a menu at a restaurant 🍴
When you want to buy desired items at a market 🛍️
When you have simple questions while using public transportation 🚌
Or in case of emergencies 😱
Instead of inputting each phrase into a translation tool, if you pre-learn a simple phrasebook for these situations, wouldn't you appear more seasoned as a traveler? 😎
