buttcrack at work

This story came from my sister in one of my family gatherings. My sister works at a office where they sell products to people. They have this bitch of a boss we will call Lucy. From what my sister describes she is this women in her mid 20s who is always being uptight about professionalism and has had it out with my sister for some reason. One day my sister comes in wearing some casual clothes since her washing machine broke and she didn't had time to go to the laundry mat. She thought it wouldn't be a big deal since she's just gonna be on the phone all day but her boss calls her in her office for violating the dress code rule. She goes into the office and she gets chewed out by her boss. The dress code at work was wearing dress shirt abd dress pants but my sister was just wearing a regular shirt. Her boss turns back towards my sister to write out a citation on her desk. Thats when my sister sees 5 inches of her bosses buttcrack in her face. My sister says she was struggling not to laugh when she saw it. Her boss stood there for a good minute with her ass out writing her the citation before turning around handing it to her. She tells my sister along the lines of "We dress professionally here so act like it" before turning around showing her buttcrack again to my sister to sit down at her desk. My sister returns work at her desk. She tells me she would see her boss walking around with her buttcrack out all day whenever she leaves the office to do something and nobody at worked warned her. When she got off work and was walking to her car she can see her boss leaving walking to her car with buttcrack still out. I asked if she reported it to hr. My sister tells me she didn't bother because her boss have friends in hr.
