Why this is funny

Sometimes, i have to draw stuff for work.(her caption)

I find this funny because I picture some bossman type figure (could be a woman) sitting xtx down, handing her a 3x3 post-it note and a blue medium point Papermate stick pen and saying "Draw" and she's all like "Draw what?" and she told "Just Draw" so she shrugs her shoulders and says "Alright" because she's still getting paid, but now she's getting paid to draw and she draws a pair of shoes and stocking that would best belong on some Dutch elf but secretly she would like a pair for herself.
