Honest Marketing or Low Self-Esteem?

Working on the marketing campaign for a new hospitality-related business:

Client: The writeup looks great, but maybe you can dial it back a little. Don’t put too much emphasis on the quality. For example, don’t use words like “excellent”, just say “good”. 

Me: Okay, I can make the changes to the text. What about the images?

Client: Oh yes, the guy looks too happy. Can you make his expression more neutral? We don’t want people to have too much expectations.

Me: Alright, but that’s the only image you provided. 

Client: I don’t mind if you Photoshop it. Just less happiness in general.
