Mr. Thornton has had his lawn mowed by Smith's Landscaping for $25 a week for the past three years. Smith's Landscaping told Mr. Thornton that they were raising their fee to $30 a week. Mr. Thornton threatened Smith's Landscaping that if it did not keep the price at $25, he would tell his neighbors that Smith's had damaged his flower beds.

Can Mr. Thornton be accused of duress?
