Rogue: Tavern Wench
You grew up working in the taverns, maybe your parents owned the place or worked there themselves. You started cleaning the floor and dishes in the back, and kept away from the people in the front. As you grew up you started serving. Serving alcohol in a tavern is rough business. The patrons, both male and female, can get handsy, they are usually drunk and rowdy, and they are not pleasant to be around. You have learned how to navigate through these challenges.
By level 3 you are very accustomed to life in a busy tavern and can easily make your way through a crowd. As such, you gain proficiency and expertise in acrobatics and are able to move through any crowd at normal speed. Additionally, you can move through enemies space in combat as normal terrain and requiring no checks.
You have seen your fair share of barroom brawls and have learned to protect yourself in them. Thus at level 3, you are considered proficient with improvised weapons and unarmed strikes and both gain the finesse attribute for you.
You also gain an additional way to use your Sneak Attack, since you are used to fighting in the chaos of a crowded bar brawl. You don’t need advantage on the attack roll to use your sneak attack against a creature within 5 feet of you, if there are 2 other creatures within 5 feet of you and you don’t have disadvantage.
Inured to Unwanted Attention
You have spent years being hit on by drunk patrons, so much so that you have become resistant to the unwanted advances and charms of others. At level 9, you have advantage on all saving throws to resist Charm effects from spells of special abilities.
You’ve spent your entire life in the tavern and you can toss them back with the best of them. At level 13, You can drink a potion as a free object interaction. Additionally, you can throw a drink, oil, alchemist's fire, acid, holy water, or any other liquid on another target as a bonus action.
Keep your hands to yourself!
At level 17, you been there and done that. Frankly you are getting pretty tired of all the s**t from your patrons. When you are hit with an attack or grappled, may use your reaction to make an unarmed strike against your attacker. If you are successful in your hit, you also automatically break any grapples.
