Lisa is planning to open a new coffee shop and is looking for some modern tables and chairs to

furnish it with. Her friend Tom is a carpenter so she asked him if he could make her six tables.

Tom quoted the price of $3000 for all six tables and said that he is currently talking to Bob, the

timber supplier regarding sourcing the appropriate timber.

Bob emailed Tom saying:

"Yes, I think I have the right timber. For what you need it should be around $1800."

Upon receiving the quote Lisa responded by email as follows:

"Good, make sure that it is a hardwood and light in colour. Let's agree that $3000 is a final price

including timber and your labour."

A few days later Tom emailed Lisa that the price has now changed to $3600 as the timber is more

expensive than he thought. He also wrote:

"Yes, of course, I will make sure that it will be hardwood but I cannot guarantee the colour as it

varies between different batches of timber. Also, the timber merchant would like $500 deposit and I

am short on cash. Does it all sound ok?"

The next day Lisa transferred $500 to Tom's account.

Some weeks later Tom delivered the tables to Lisa but she was not happy:

"These are just too dark! I asked you specifically to make them light in colour. Take them away and

I want my $500 back!"

Tom was really upset and said:

"You cannot do it! We have a contract! I don't have any money left after I paid for the timber and

even if I wanted I cannot pay you back the $500."

Lisa responded:

"No, we don't have a contract! I never signed anything. And as I still own you $800 from our trip last

year, keep my $500. Now I don't own you anything."

Question 1. Does Lisa own Tom anything?
