Maybe they get lucky and someone desperately wants to dump some sats 🤷‍♀️ 

 No, it means they get more sats. 

 Makers set the price so if someone does Premium -14% they're saying I'll trade with you but it's going to be worth it for me. I regularly get sats 10-15% under market price.
 

 There is often not a lot of liquidity. If you put it out there you might get lucky 

 Maybe the default presumption is that anyone willing to sell sats for fiat is probably not very smart.
