you own a lawn care service. a new customer calls and asks that you mow and weed eat her lawn. you tell her the price will be $150
and she agrees. you show up while she is at work and get the lawn mowed and the weed eating done by the time she gets home.
unfortunately, when she gets home, you discover that you have serviced the lawn of your customer's next-door neighbor instead of
hers!
do you think you have any chance of getting any money from the neighbor for the services you have provided?
