I'm wondering whether or not "Likewise" should be followed by a comma in the following dialogue:
A: Hello, you must be Peter.
B: And you must be Sam.
A: That's right. Welcome to Boston.
B: Thank you. It's such a pleasure to meet you.
A: Likewise, all the staff at PC Mart are looking forward to meeting you and your team.
Could "likewise" be taken to mean "with the same pleasure" in the above and the use of a comma justified?
