When You're A Dory 🐠

So I remember things if they have an order, story, or some kind of relationship to them. I do pretty well in school because I don't memorize everything, instead I relate it to stuff I already know. But if it's just random short term things; forget about it, literally 😂. My manager gets frustrated with me at my job because while I get most stuff right, sometimes I forget table numbers and things like that. It's my first job and I want to do well and I'm under more pressure since I'm the youngest employee (everyone else is in their 20s-30s). Any advice for short term memory loss?
