There is this guy..

He is a weiter at a bar im visiting all the time.. he worked there before then took a break and now he works there again.. before i was always looking at him but i didnt want him to see me looking, but one time he did and he smiled.. then now when he came back i was at the bar just chilling and he didnt ask me what i will drink..of course i was again checking him out and he saw me so instead of avoiding me he came and asked me with a smile.. unfortunately i had to go.. i dont know if he is into me or? Im really afraid to talk ti him, idk how lol..Also he is a bit older then me but I dont mind it.. please give me some advice!
