say hello to a year-ender pissed off empathy!!!

i don't exactly know how to react to this totally bizarre & demented situation. so i'm asking YOU! why on earth have u been so dumb all this time???
last year, you came to my mom's clinic (and apparently, i was there too!) and saw that 150gm kojic soap. you were amazed at how cheap it was. and you even said that my retail price is the wholesale price of 100 bars from your previous supplier. and that's where everything started- -our business transaction. and since you're some-kind-of a "friend" of my mom's, i gave you a much lower rate, so you can sell them at your *renowned pharmacy* and gain more profit. (yeah, you were selling it at 25pesos more than my retail, and now you'll be selling it more than that pa!!! congratulations!!!)(yes, i admit. i do not sell just to make money, i don't even have a huge profit for this. i sell because i want to share the positive effects of that soap! *damn you!*) so i delivered 50 bars at your *renowned pharmacy.*
months months months later after that first transaction, you called again and ordered another 50bars. i was happy that you did, so i prepared them and you technically picked them up at my mom's clinic on purpose. still the same price.
and now, after maybe more than a year. you called again. 50 bars that is. so i prepared them again, and you again said you'll just pick them up at my mom's clinic, hence, again. (28th of november) now 170gm, i gave you the exact same price as before. but what happened? a few hours after your some-kind-of-a-son picked them up, you sent me a text message, somehow angry. angry because you thought i gave a 20 peso increase. and that your son's angry too coz he just brought with him a little extra mullah and he had to pay more than what you handed him to pay me. i keep on explaining that i did not, and that for the record, the rate i gave you is the cheapest & lowest among all the transactions i've made! but you still insisted, that i made a note to the 1st transaction stating bodly the price --and t'was 20 pesos cheaper. whut!? how and why!? yes, i don't sell to make a large amount of profit -- but i would never sell it at that rate that your claiming did! that would make me a foul, dumb, stupid fool, don't you think??? (nag negosyo pko, kung magpalugi lang diay ko!!! bugok.)
and as of last night, 14th of december. you sent me a long text message, telling me that you'll return what you've ordered. you insisted still that my rate went up 20pesos higher. and that your selling price is 13 pesos lower than how much you got from me. isn't that stupid? you just fell 45pesos off from your first selling rate at your *renowned pharmacy!* ano yan, baclaran??? and since i was so damned about it--i simply gave you my kindest reply of "K" shush you're noisy blabbing mouth!
i'm thinking, should i charge you for a surcharge? i know my mom wouldn't like that. but hey. business is business. and i 100000000% sure you know that so well. you have 3 branches of your *renowned pharmacy* here. so you pretty know how everything goes. but i don't know --i think because i'm 2 decades younger than you, i still should respect you even a little. so i guess i won't. and because of that, you deserve this blog. damn. you. i hope you *renowned pharmacy* will continue on until the end times!
