>>72166730OG numbers anon here. Not going to weebcon but I was at anime expo and did several meet and greet with liggers at that event. The key thing outside of hygiene and such is to respect boundaries. A lot of the liggers at this event are there to have fun so if they are off the clock (aka not at a meet and greet), give them their space. If they are OK with meeting fans they will either state it on social media or discord. At the meet and greets or panels, just be polite and be respectful. Even if you think you are spilling your spaghetti ,they usually won't care as long as you play it as cool as you can. Target events or panels you want as a priority and focus on those so everything else is a bonus. Most of all, just have fun. It will be a good memory.
