Grace Smith was still on the ground, and she looked at the liquid under her feet. The liquid was definitely not plain water. It must be some kind of slippery chemical.
"Please wait a moment." She looked at him.
Heinz Jones pursed his lips and frowned.
"Let me clean my shoes first," she explained, "I can't be on the ground while talking to you. Oh, by the way, what's wrong with the cleaning department of your company? The liquid on the ground was so slippery. Why didn't anyone come and mop it away?" Grace asked.
Then, she opened the zipper of her purse, took out a pack of tissue paper, and spread the sheets on the ground. Then she stood up and stepped on the tissue paper.
Heinz frowned looked at her with frowning brow and spread the paper on the water stain just now. Sure enough, it was very slippery.
