Reb Eliezer,
“I call myself Reb Eliezer to encourage respect to the elderly”
There’s a story of Rav Moshe Feinstein ZT”L (I think I read it in the Artscroll biography) where he was walking down a street, and a man drove by and called out “Hey Moshe, come here!” to his young son who was also on the street. Rav Moshe walked over to the car, greeted the man, and asked what the man wanted. The driver was floored, and said that he would never refer to the Rav by his first name, or make him walk over to the car. Rav Moshe was completely nonchalant and assumed the man was calling him over!
