You have an event for it so why the timer ?

(Not real code, the names are wrong)

pawn Код:

OnPlayerChangeInterior(.......)
{
    switch (newinteriorid)
    {
        case 3, 7, 9 :
        {
            if (IsPlayerInRangeOfPoint(...............) ShowPlayerTextDraw(.......);
        }
        default: HidePlayerTextDraw(.......);
    }
}

You only need one global textdraw also as the text won't change, example: "you are prohibited from entering this area", always show the same message then no need to update it or whatever.
