2.4 $m/s^2$ upwards
The customer is moving downwards at 1.24g = 1.24*9.8 = 12.2 $m/s^2$ and the coin is moving downwards at 9.8 $m/s^2$. Setting the man as our reference point, he sees the coin as moving at -9.8 - - 12.2 = 2.4 $m/s^2$ upwards because he is falling down faster than the coin is and so the coin appears to be moving upwards to him.
