As I know CrazyBob's server, they're using textdraws, and then detecting if a player is seeing a certain textdraw, and writing one of the numbers that on it.

Example

pawn Code:

new Text: test;
new bool:IsSeeing[MAX_PLAYERS];

public OnGameModeInit()
{
    test = TextDrawCreate(x,y,"~y~1 ~w~This is item 1~n~~y~2 ~w~ this is item 2 ~n~~y~3 ~w~this is item 3");
    More textdraw info here
    return 1;
}

public OnPlayerEnter24/7store(playerid,24/7storeid) // Randomized as possible
{
    TextDrawShowForPlayer(playerid,test);
    IsSeeing[playerid] == true;
    return 1;
}

public OnPlayerText(playerid, text[])
{
    if(text[0] == '1' && IsSeeing[playerid] == true)
    {
        SendClientMessage(playerid,0x00,"You've chose item 1!");
        IsSeeing[playerid] = false;
        TextDrawHideForPlayer(playerid,test);
        return 0; //So everyone won't see he wrote '1'.
    }
    if(text[0] == '2' && IsSeeing[playerid] == true)
    {
        SendClientMessage(playerid,0x00,"You've chose item 2!");
        IsSeeing[playerid] = false;
        TextDrawHideForPlayer(playerid,test);
        return 0;
    }
    return 1;
}

//ETC.

Got that?
