Lucinda was shopping in Bigmart in the women's department. After about 10 minutes, she gathered her shopping cart and began walking out of the department. Suddenly she slipped and almost fell. She hit her leg against the shopping cart, and it began to swell. During her fall, she noticed a "gob" on the floor. A Bigmart employee later said that it looked like someone had spat on the floor, like it was phlegm. Under the reasonable person standard, did Bigmart breach a duty to Lucinda by not cleaning up the gob?
