Bad Guest habits (trade and other games)

So, as the counterpart to the earlier thread on bad host habits, this one is dedicated to those annoying things that non-hosts do in a game. Whilst my angle is more on the trade game side, do feel free to add your irks for Tz and other games too.

A few to start you off...

1. Coming into the host's game not to buy, but to offer the same item, especially at a cheaper price. Sometimes this is down to the guest being new to trade games (and most will gladly leave when told to), but sometimes, it isn't. IMO this is just disrespectful to the host.

2. Coming into the host's "need: x" game whilst host and another player is mid trade/negotiation, just to drop the x item on the Ground free of

Charge. Whilst this usually delights the host enormously, it has the side effect of ruining someone else's transaction. For such items, usually we are talking low runes/ pgems / lower value, but I mean, here, whilst the motive is usually a benevolent one, IMO it is disrespectful to the other player. I mean, at least wait until it looks like they've finished negotiating before you offer... This i suspect might be a more controversial one.

3. Coming into the host's o: x n: y game and insulting the ask price + obvious lowballing. e.g. your 3/20/20 is the football type, which no one wants. i'll offer 3 pgems for it. Comments exaggerated, but you get the picture.
