I’m a waitress and I feel watched

I’m a waitress at a sports bar in my mid 20’s, and the restaurant I work at is located on a street with a lot of bars and clubs. <br>The street is usually pretty busy on the weekends, and the restaurant sees a lot of drunk patrons, especially in the mid-morning hours after the bars and clubs close. <br> I’ve been working at this restaurant for about 6 months now, and I used to notice this one guy coming in and sitting at the bar every week or so. <br>He’s a very tall and skinny white guy, about 6’6, with greasy black hair that reaches his butt, and really white skin. <br>He also has really bright green eyes, and he always stares at me really intensely. <br>He always orders the same drink, and never says anything to me except to order his drink.<br><br>He used to come in alone, but he now always comes in with 2 other guys who kind of look like him, tall and skinny, with black hair. <br>They always sit at a table, and leave after about an hour. <br>I notice they have never ordered food, and only order drinks, but they usually always leave a $100 tip. <br><br> I can’t help but feel like I’m being watched, I feel like their staring at me the whole time, but I don’t want to seem rude, so I just try to pretend like I don’t notice. <br>One time I went into the back to grab a jug of cream, and one of them followed me in the back. <br>I thought it was weird at first, but I figured he was trying to find the bathroom. <br>But then I hear the bathroom door close, and it’s a singular bathroom, and I see a coworker of mine come out of the bathroom, so I’m confused as to why he’s still back there. <br>So I turn around trying to find out what he’s doing, and he’s standing right behind me, so I got a little startled, and jumped back. <br>He just kind of laughed and said “oh sorry”, and then he just walked out, it was really weird. <br>Ever since then, I feel watched, I feel like they’re watching my every move.
