Question 92 - 94 refer to following paragraph:

M: Hi, this message is for Ronald Belson. (92) My name is Stuart Lawson, the manager at Rosewood Printing Company. We just received an online order from you for 2000 wedding invitations with lace and gold fabric wrappings. (93) I’m calling just to confirm your order is for 2000 invitations and not 200. It is unusual to get such a large order so I just want to make sure it is correct. Please call me back to confirm when you have a chance. We will not proceed with the order until you confirm. (94) Also, if you are planning such a large event, we have an excellent planner in the office named Shubert Mendez. If you want to speak with him just ask for extension 12 when you call to confirm. I will make sure he gives you a free consultation.

92. Who most likely is the speaker?
