We were excited when we heard O'Shea's was coming back so we made a point to visit it new at the Linq.  Well, everything was all fine and dandy until we met this one bartender.  We visited in May and just recently in June.  In may we came in for some shots as a group and met this bartender that initially seemed great...bonded with the group...provided water...so far so good right?  Wrong.  When we get our bills we find that he overcharged us for our shots.  When we pointed it out he was like \"Oh Crap, my bad, I'll have to call the manager to reverse this but it might take a while.\"  Then he asks us if we would rather just have another round of shots to make it even and forgo the hassle....okay fine we ordered another shot each.  Unfortunately when he gave us the shots it was not what we ordered, it was a cheaper shot and he said \"Well these are better anyways\"  Ummmm pretty sure you just charged us for a more expensive shot and gave us the cheapest one you have....We left feeling scammed. \n  Okay, so we try it again in June for my husbands birthday.  More shots.  Lo and Behold we get the SAME bartender and this time I wanted to see if he would do the same schpeal.  Sure enough when he brought my sister in law's change back he was like \"oh! my bad I over charged you...too late now right\"  at this point we were like um no she wants her change.  He then says okay well i'll have to call the manager and it could definitely be a while.  When I mentioned that we had been there a month before, suddenly, he comes back with her change saying that he \"would just eat the difference\"  Trying to make us feel bad ...hmmmmm....yes you will buddy cuz you are scamming people.   At this point we asked for a manager to let them know.  Not sure if some of the other bartenders were in on it or not.  The managers did listen to us and will hopefully fire this one bartender as he is scamming people.  They also offered us a couple free rounds of drinks each for our trouble.  Over all we MIGHT come back to O'sheas because the managers were nice and helpful but if we see that bartender again...NO WAY.
