About 12 years or so ago, I saw this cliche played to the maximum.There are also players who refuse to follow the DM's guidelines on what classes they want.
Such as if the DM wants to use only the PHB, no ECL characters, and no prestige classes, a character will make a class from a book like the Complete Adventurer Book and whine whine whine whine whine until one of two things happen. Either the DM relents or simply says "then don't play". If the latter happens, the player goes off whining about how the DM is a bad person.
It was 1999, so the game system was AD&D 2e. I was running a quasi-historic game set in the 12th century (but with some magic and fantastic elements, but definitely low-magic by D&D standards).
He asked if he could play in the game, I honestly didn't care much for the player so I waffled and gave an "I'll think about it".
I mentioned how I used a point-buy system for ability scores, no Evil PC's (and Chaotic Neutral requiring special permission), only human PC's were allowed (again, historic game), and the only classes that were allowed in unrestricted were Fighters, Rangers, Paladins and Thieves. Arcane magic was extremely rare and relatively low powered, so he'd have to get a copy of my weakened Wizard spell list if he wanted to play one (and understand he'd have to hide his magic or be hunted as a heretic), and Divine magic was also downgraded (but not as badly as Wizards), so a Cleric could be played but they'd have a reduced spell list.
He shows up the next day at lunch with a Lawful Evil Elven Fighter/Mage/Thief (with the Spellfilcher kit from the Complete Book of Elves) with multiple psionic wild talents (Disintegrate and Dimension Door?!?), and 3 18's in his ability scores which he swears he rolled up legitimately.
I repeated to him: point-buy for ability scores, no evil characters, no elves, no psionics, nothing from the Complete Book of Elves, and most of the spells he chose as wizard spells were right out.
He then began to whine about how they were all "standard options" from official books and every DM therefore had to let them it, it was right there in the rules, and he rolled it all up himself (including the ~1% chance of psionics, and the >1% chance of rolling up those insane power combinations, and three 18's and no ability score below 16).
He didn't join my campaign, and he made it clear he thought I was a mean, bad horrible DM who wasn't fair to players, and shouldn't be allowed to DM anymore, and griped about me to everyone who would listen.
Apparently that was his "standard' D&D character he tried to join every game with, he asked everyone who was running a D&D game if he could play, then demanded that exact character, stats and all. Not a single DM I knew allowed it.
