I saw a concocted, unnecessary word – “vends”, used only in North India. It probably means “alcohol vendors”, which is the word to be used if communicating with educated people outside India.

I still hear Indians saying, “What is your good name, sir?” (Sometimes, it is “sirji”.)
Stop translating from your Indian language, such as Hindi – “aap ka shubh naam kya hain?”
Although you were brought up to be polite in India, you are going to confuse foreigners, who don’t have good or bad names.
If you don’t want to say, “What’s your name?”, just shake hands and say “Hi, my name is Monnanda Appaiah Deviah” and they will respond with their name, or their jaw will drop and say “I beg your pardon?”.
