@ colorblack---- The only way he knows he made a mistake is because the buyer messaged him and said so. So lets say I shipped out 50 pills and the buyer says " hey rx I got my package and I actually had 49 not 50" I would respond" Sorry about that...it was a mistake obv, I will send you another 1 or I will refund you...you tell me...sorry" So I would say I made a mistake as would anyone else ..I think that is the correct lingo you would use if you were a vendor...Unless of course you knew for a fact it was not short...then you would send something like this " Hey you lying fucking asshole. I know it had 50 in because it is counted by 3 people and checked off by each person BEFORE it is sent..so no mistakes are EVER made! So quit fucking lying and enjoy your package because that is the last one you will ever get from me...you lying fucking dirt ball loser!!" or something like that Never happened..and that's why. Though obv it is a lot easier to mess up with scales. @HeatFireFlame Wow Mr. conspirator! I don't think you read the OP's full post..if you did you would read that the vendor got back to him and said he clearly made a mistake and he would fix it. So the last paragraph of your message doesn't really make sense...No biggie..
