Bouncer

Bouncers are NPCs that appear in The Urbz: Sims in the City, The Sims 3: Late Night and The Sims 4: Get Famous. They appear in front of entrances to various celebrity driven community lots to keep non-celebrity Sims away. However, there are many techniques that non-celebrity Sims can use to gain access in to these places.

The Urbz: Sims in the City
In The Urbz: Sims in the City, the player must earn REP and dress (only the shirt is required) according to the districts to get past the bouncer so they can access the midnight party. If the player does not have enough rep, the player will get a message saying the player needs more rep. If the player does have enough rep but isn't wearing the correct shirt, the player is asked to change their clothes.

There is a glitch that can allow player Urbz to get into the VIP room even if they are not legally allowed to enter. The trick involves 2 player Urbz in the same district.

Bouncer cannot be socialized with in The Urbz: Sims in the City.

The Sims 3: Late Night
Bouncers in Late Night prevent certain Sims from entering clubs, bars, and lounges. Bouncers are "summoned" to a venue by placing a barrier rope next to a door or arch in build mode.

Sims can rely on their celebrity status to get into venues, or they can hack, bribe, or sneak their way past a bouncer. Players cannot direct their Sims to flirt with a bouncer in order to gain entry to a venue, though a high relationship with the bouncer can yield access. Sims can use the teleportation pad or zeneportation to simply teleport past the bouncer. Playable ghosts can simply walk through the wall and avoid the bouncer entirely. Sims may attempt to sneak their way into the club, although they will be reprimanded by the bouncer if they are caught. Bouncers may occasionally leave their post and go inside the club, such as to get a drink; this provides Sims with an excellent opportunity to sneak in without getting caught. Other life states may be able to use their abilities to disable the bouncer; vampires can hypnotize the bouncer if they are powerful enough, while witches and fairies can use their magic to distract or drive away the bouncer.

The game draws bouncers firstly from the pre-existing pool of homeless Sims in a neighborhood. Sims are randomly assigned as bouncers unless the player uses a mod.

The Sims 4: Get Famous
Bouncers return in The Sims 4: Get Famous. Like previous games, they guard doors and prevent Sims with too low of a fame level from entering (the default level they allow is three stars or higher, which can be changed). A bouncer is assigned to each bouncer door that is placed on a lot, allowing for multiple bouncers at a venue. Sims who aren't famous enough to enter can either bribe, convince or fight bouncers to gain access, but all of these actions have a chance to fail. Occult Sims can used several abilities to bouncers in order enter. Vampires can hypnotize bouncers if they have enough power, aliens can use mind controlling or freeze them so they can enter without caught,  mermaids can use singing power to hypnotize bouncer who mistakenly thinks them as a celebrity,Spellcaster can use magical power to tricking bouncer (e.g. they casting illusion to them. Thinking the club is burned) so they can sneakly enter. Although it doesn't serve as a problem to normal Sims, lower star celebrities might get caught by paparazzi and get publicly disgraced.
