Aren't you glad that they didn't turn down you when you were inexperienced?
Since I often travel solo to resort areas, I have dived with lots of different buddies.
The quality of buddies doesn't depend much on experience level.
The quality of a buddy seems to be more related to general attitude and their overall "got it togetherness". The same personality you see on the boat is going to be there underwater.
The quality of a random buddy is also highly dependent upon how much effort we put into getting us on the same wavelength before the dive starts.
If you keep running into "bad buddies", you should look hard and critically at your own predive skills. My random boat buddies got much better once I became more clear on expectations about things like buddy-to-buddy distance and relative positioning, signalling of general changes in direction of movement, turn times and pressures, etc.
