Alec Baldwin allegedly 'yelled' at a female server at Thursday night's PEN America Literary Gala in NYC - leaving her 'shocked and upset', reports Page Six. <br /><br />The actor, 65, who made his return to the red carpet after all charges were dropped against for accidentally shooting and killing cinematographer Halyna Hutchins on the set of Rust - is said to have become frustrated when the server began delivering meals to a table while he was on his feet chatting to a fellow attendee. <br /><br />A source told the publication the incident unfolded when Baldwin stood to chat with someone a 'couple of minutes before the line of servers come all at once to deliver the meals.<br /><br />The server, said to be in her late 20s or early 30s, was allegedly stuck behind the actor as he was chatting, with the source saying: 'Then, when she could pass, she started putting plates on the table. I guess he didn’t like that she did that with him standing there.'<br /><br />The actor is then said to have started 'scolding her' with the 'visibly upset' server overheard telling someone: 'I don't know why he yelled at me.' <br />
