PED are not as important as respect and politeness
we are herre to have a break from RL..
If respect and politness is important, I would in the OP's argument say that he was correct, and the auctioneer, is a massive toolsack.
I'm not entierliy sure why, but the way a lot of people in EU interact with other humans, makes me think that the vast majority of the game are Karens and Kyles who think they litterally own the entire world.
Overall though in regards of OP and general, if you see a item on auction, in 98% of the cases, its like people say, it is what it is, and take it or leave it. Either wait for it to go down, slap a bid on if bid alligns, or wait. This 98% covers any and all items that are common enough to pop up at least 3-4 times a week.
the last 2%, rare stuff you'd generally never really expect to pop up nearly as frequently at all on auction, sure, stalk the person whos put it up. send them a PM and politely ask, I do it all the time. If a item is put on auction, that is vastly over MU and not often put up, ill ship them an offer and ask if they'd be willing to wait a few days and if its not sold, or wait till the auction ends and sell it to me for my offered price. Sometiems if its something with a 7d timer ill ask if theyd take fee + offer instead.
That is not rude at all, and ya'll just need to settle down, calm your stallions and step of them.
As for the OP though a lot of people really dislike "traders". And see trade spammers and traders as the litterall scum of EU. Inclined to agree as there is no case ever where a trader will not scam you in EU. I know its a opertunistic thing, but like come on lol, they need to stop pawn stars,
and in THAT regard, OP asking for 5 ped under what is already a low MU, is a classic case of "Oh you mr trader, you and your silly shenanigan scams!"... Its not without reason i always joke about traders in that, they will offer you 1 ped for an item, and in the same breath do a 180turn, and resell it for 1000. When they buy, they will argue and negotiate ever dime to squeeze stuff as low as possible. when buying of them, they will not budge at all and instantly ignore you. I'm sure there are som traders that wont just try to scam and rob everything breathing, or not breathing. But untill the day i run into one of those, they will be the worst people i now of in EU sadly.
The auctioneer, could have given a more polite answer to a stranger, but since it was a trader, imo it was ok. After all, mr trader, you could have bought it for 145 on auction, and still made profit
