Keeping clients happy

i think they should realy take customer complain serious , and make and keep people happy most of the time you will find rewards customer complain and sit and swear and banging the machines as they didnt win or you can play without gerrting any free spin's you will keep on getting 2x symbols but to no avail,/ luck or when you do get free spins it does'nt pay any , thats why the casino its empty and people go somewhere else , back in the day with draw competitons you will find that traffic will block the entrance when you get inside it will be full and people will be excited all machines will be occupied they will speak highly of how they did win and will go home with a smile, today people is full of complains and irretated , and yes its also frustrating cause as you play on a machine it will just stop in the middle of the game you will search for 20+/-min to get hold of floor assistance to come and assist you/ or come to once aid , when you keep the client happy they will return in numbers if not the casino will remain empty, and dont give free play and when get to the casino its already expired and the desk assistance will tell you that you can come back the following day before 6 why must you set time as long as the client can be kept happy why not cause the following day they will just return with a smile as the service was up to standed.
