Just got certified, and I absolutely love the shop I got certified with. However, all of their upcoming trips are full, and I really want to go out with a group. Is it ok to go on a trip with a different shop? Are people typically loyal to only one dive shop? Should I only buy equipment and go on trips at the dive shop I got certified with? I don't know if there's some kind of etiquette about this, and I don't want to offend anybody if I explore different shops. Are dive communities centered around specific shops, or do divers in the same area tend to band together and form a community?
