Que tiene
 

so a customer walked up and i'm pretty sure she said qué tiene? that just means what do you have, as in, what are you selling right? or is there some other meaning? i know this is a dumb question but i froze and didn't know what to say so she ended up walking off.

Yes, you're right, it means What do you have?


I don't find another meaning.

Que tiene also means What's wrong? or What's wrong with you:o--especially when you say it this way: ¿Que tienes tú?

that's right it means "What do you have".

I sure hope she didn't mean what's wrong with you!! I'm so mad at myself because this happens to me a lot. A customer will say something in Spanish and I know what they say and I know how to respond....but then I hesitate....and so I get stuck between saying lo siento no hablo español and answering the question....so it either comes out in inaudible Spanish snippets or in english. Either way they leave. It is so saddening :(

Don't let people discourage you. If you are reaching out to them, and they
respond rudely, that's their problem. If someone asks you, "que tienes"
Answer "Muchas cosas. ¿Qué necesitas?

Yes, I can understand your situation, but really if you've no idea above is telling the you the costumer, then you should to try understand the little Spanish that you have learn before, I believe that it could to work you as a little a fast practice also it can work as method to learning for you, don't worry really you have time although customer hasn't time, to think about the was wrong in that moment.;)

If she walked up to your stand/store and asked ¿Qué tiene?, yes she was asking what you have (to sell). As already mentioned, the phrase has other meanings as well:

¿Qué tiene? = What do you have?
¿Qué tiene? = What's wrong with you/that?

Exactly really she was asking him, if he has something to show her. ( To sell )
