These may be pet peeves of some other people but I'm not reading 50+ pages to find out.
Printers. I hate printers with a passion. They stop working for no apparent reason, people seem to find a need to be linked to every printer in the office and if you miss one during a reinstall or upgrade they're on your **** the minute they realize it's not there. I've printed exactly 1 piece of paper at the office this month and I see no need why anyone else needs to print more than that. I just upgraded a computer here at work and the broad that uses it is hooked to five printers. Five. WTF?
I hate eBay bidders that insist on being the top bidder on an item no matter what. There is no need for a bidding war on a relatively common item on day 2 of a 7 day auction, especially when it's an item that should sell in the $20 range, for example, and it's already up to $15 or $18 with 5 days left.
I also hate it when I list an auction and the first line says "No 0 feedback bidders" and my first bidder has 0 feedback.
On top of that I always list my auctions stating that non-US winners will be quoted a shipping price at the end of the auction and I tell them why; the USPS calculator sucks, there are 3 valid ways to ship outside the country (ground, air parcel post and Global Express) and rather than people complain about high shipping I always charge the exact amount which means boxing the item and getting a quote from the Post Office.
First day of my recent listings I got 3 "how much to ship to XXX" where XXX was UK, Canada and Australia. The rest of the week I also got Spain, UK, France twice, another Australia and 2 or 3 more from Canada. NONE of the people that asked ended up winning although most bid. And that's why it's a waste of my time to estimate shipping during the auction and why I tell them that...but people are ******* idiots. Last I knew, Canada, UK and Australia all spoke English so they don't have an excuse. I expect that US bidders will not be able to comprehend a basic sentence but I hold these other countries to higher standards since they like to poo poo the US on our apparent educational shortcomings. And people wonder why US sellers don't like to ship overseas?
E... (who hates everyone equally because it's less confusing)
