thank you, everyone for helping me find the best way to do this. i understood that donating 50 or 100% is the only way to go and what i originally thought as a well persived idea - will not look as such, so the best thought i read was - to have a day at which i will donate 50 to 100% of sales, say, on mondays. now, how is that going to be percieved? - people not going to say -why wont you donate all your friday sales? probably not, but i am a bit concerned now how seemingly good thing can be seen as negative by others, and even if just a small group of my customers will see it as such - i should probably better off not doing it. Now, i am thinking about doing it for maybe next 8 mondays, and understand that donating all proceeds is much better than half, but keeping half would really help me pull this off, what do you think? i also thought of this - instead of ringing up orders and charging them, and than donating … well maybe i should just have a big bowl sitting on a counter and people just put whatever they think there order is worth or even whatever they feel like donating or not donating, i will not be forcing them to put anything in a bowl, and at the end of the night whatever is there - donated, but what if some people take advantage of that and will be there to just grab a free pizza and than call their friends? please help me get this thing right.
