Obviously if she left the papers in the kitchen and sent you a text that there's chicken in the oven, she wanted you to see the papers. Something like that doesn't just get left out on accident.
Also, it's my understanding that SHE CAN'T serve you the papers herself. It has to be done by someone else. I would just take them, sign, and walk away.
