Post-covid cons have had an influx of attendees who have never been to a con before, and that's great! But I've also seen a rise in some slightly inconsiderate behaviour so I'd like to do a little post on what is generally considered good manners when attending a convention:
1️⃣ Ask before taking photos, whether it's of cosplays, stalls, traders, or merch. It's very rude to approach a table, take a photo of their stock without asking, and leave.
2️⃣ Don't comment on the prices of merchandise at exhibitors' tables. If you think something is too expensive, keep it to yourself; traders need to make money from their art and have likely already priced items fairly. Related, but in general don't make negative or jokey comments about someone's merchandise in front of them. Or at all, honestly.
3️⃣ Don't try to haggle or ask for bulk discounts. Conventions are not farmers' markets or retail stores.
4️⃣ Please try not to take up too much of the exhibitors' time by chatting. It can be really exciting to meet a creator, and a lot of traders are really friendly and enjoy talking to customers, but please remember that this is also a workplace for traders and they need to sell. If an exhibitor excuses themself because there are other customers waiting, this is usually a good point to thank them for their time and say goodbye so they can continue working.
5️⃣ Try to avoid placing anything on the exhibitors' tables, including bags but especially drinks and food. This can at best mess up a display and at worst ruin merchandise, putting exhibitors out of pocket.
6️⃣ If you are waiting to look at one table in particular, be courteous of neighbouring tables. Do not stand in front of other tables because you are queueing or just standing chatting with friends, as you are likely blocking other potential customers from seeing that table.
7️⃣ An extra point raised by @pppondi - feel free to ask to have a look through books and comics, but don't read the entire thing then put it back. That's why they're on sale, so you can read them!
☀️ I really do hope this helps someone! Some of these guidelines might not be obvious but it makes for a better con experience for both you and the exhibitors; traders are less stressed and you get to interact with happier creators. If you have more suggested guidelines for people who are starting to attend cons please feel free to share, but also remember that a lot of shy, anxious, and neurodivergent folk attend cons. I'm trying to be constructive, not just list "weird" behaviour.
