If the turn doesn't complete the flush he will try to push you around hard since he has you pegged on the wrong hand and figures his low/middle pair are good. You, of course, can push back harder.
If he raised you and the flush completes you can be pretty sure you are REPRESENTING the best hand and bet accordingly. Even better if he bitches at you for being a bad player and chasing the flush with bad pot odds after he folds.
Though I can understand the helpfulness of confirming what your opponent has, aren't you kinda giving a card away? Isn't that small bet just like a check + information? Why don't you size your bet to chase out draws. If they fold, you know what they had AND you have the money. If they call and they get their draw, you just paid extra to know to fold (you could have found that out with a check just as easy).
