Another day, another super idiomatic chunk with quedar ;)
Here's what this one means:
👉 to let someone down / to look bad
💡 In Mexico, you'll often hear te quedo mal as a polite way of saying I can't help you (when asking for directions) or I don't have what you're looking for (when at a market).
🌪️ When to whip it out
Whenever someone didn't show up, flaked on a promise, etc.
No le avisé que no iba y quedé mal.
I didn't tell her I wasn't going, and now I look bad.
Si no terminas el trabajo, vas a quedar mal con el cliente.
If you don't finish the work, you're going to make a bad impression on the client.
