Why would my male personal trainer make a face at me talking about my guy friend who goes to the gym?

I asked him what he thought of my wrist straps then he said they’d re quite good bjt different to what he uses i then explained my friend goes to the gym and stuff and be like recommended them so I got him they’re the ones he used and my trainer made a face like very blantantly like a “wtf” “cringe face” then he said don’t worry about the straps just worry about looking good I’ll take care of that
