I had the misfortune of experiencing a delivery disaster with Walmart recently. The package I received was damaged beyond belief, as if it had been tossed around like a football. Customer service was a nightmare to deal with, offering no real solutions or apologies. It's a shame when a company as big as Walmart fails so miserably in basic delivery standards.
Airbnb is a wonderful way to find accommodation while traveling. I've used their services multiple times and have always been pleased with the selection and quality of offerings.
I rarely visit McDonald's, but when I do, I'm usually satisfied. The food is prepared quickly and the prices are quite reasonable. However, the quality can sometimes vary.
