It's just been a couple days since you talked, there doesn't need to be a conversation every single time you see each other just because you were texting.1THIS IS NOT RELEVANT ANYMORE

It could be that with the Bud 'Working with us today,' he finds this a bit awkward and doesn't want to Have to Explain Anything to Anyone if he should catch on To... Some friendly flirting.
Maybe later after the doors close, you could push a button your way to find out if he Is... Okay. Find out if he had something on his mind on the job, that he Wasn't... Himself.
However, if he doesn't reply or even if he does, and doesn't say Anything worth Answering your Question, then go to work tomorrow and see if he is this same way and if he Still puts you on his pay no mind list.
After This, take it that there is nothing left to say and ignore him then.
On the record, the 'Showing Off' you saw him doing was just This: Showing Off in front of everyone for fun but at the same time, this also shows me, he is a bit nervous and this is his way of Releasing it.
Good luck. xx0THIS IS NOT RELEVANT ANYMORE
