Sure, OPT算是legally authorized to work in the US, but only for one year. You don't need to tell them that you only have one year. If they ask you if you need H1B, you should say 'Yes'. They may or may not be bothered by your F1 status.
Once i saw an asian lady at the customer service counter waiting and holding a dolly with flat tires... and one of the sales associates said to her: done using it??? very embarrassing... of course the stupid clerk end up appologizing, as the husband came back with a set of new replacement tires... they were there to make a purchase with their used dolly that did not come with high quality wheels, so the clerk ending up helping them installed the wheels. it is okay to return sth that is really not functioning as expected otherwise if you yourself think it is hurting RP then dont do it.
