People like this are why I dive solo most of the time. In my first 40 years of diving I only dove with 5 people, 3 of them only once. Only in the last 5 years have started to dive with new people, most of them very new to the sport. I prefer to dive with someone new who is still interested in learning rather then some jerk with a fist full of underwater basket weaving certifications who thinks that they know it all.
