You are a contract manager for ABC Construction Co. ABC receives an invitation from John, a landowner, to submit a bid for building a new skyscraper on his property. You reply to the invitation and submit your best terms which you believe delivers higher quality at a lower price than your competitors. That same day, you receive an email from Zappo Electrical Inc. offering to support an ABC construction project for $20,000. Zappo states, "I'm sure we can provide you the best service. If I don't hear from you in three days that means you want to work with us." You do not reply to the email, and three days later Zappo emails again, "Glad we have a contract and I look forward to working with you shortly." Does ABC have a contract with John or Zappo Electrical Inc.? Explain your answer.
