i understand u summer n i also had the same incident like urs, i went to a convenience store near my apt to make money order of $150, i withdrew $160 from my account n gave to the m f..kr, but when he counted that he told me there's only 100; i got really surprised n told him that I gave him 160 but he told me tht's all he has n i was about to return but i was 100% sure i gave him 160; when i was about to leave he saw my face being very nervous, due to this he might have thought i m gonna do sthg wrong to him or sthg went wrong itself meaning the money fell down to the floor in his side, he called me n told me here it is n i m not tryin to cheat u, Not tht mthrfkr but me got very ashamed of myself n told him nthg since then i started goin to some biggerplace for all those activities, i agree wid u they try to cheat n they r makin a big money by doin this n nobody is able to control all these shits whether here in US or other parts of the world
