Waaaah Waaaah Waaaah.....Jesus man. You logged into TERB on Christmas Day to whine and bitch about this.
Reality check for you and anyone who wants to cry about modern POS systems at any business:
-You're not that special princess. They will not remember if you tipped or not the last time you were in for a haircut or especially for a fucking oil change. Get over yourself, you're just another customer.
-Why was this added to a POS system? Because for anyone who DOES want to tip would previously have to pay separately or ask to have the POS amount increased which would not match the invoice and throw their bookkeeping off - you know, running a business and all that.
'Begs for a Tip' - Only in your mind there sunshine. Seriously, read your post, read mine and maybe, just maybe have a breakthrough that the POS is used by everyone - people who choose not to tip and those that do - having no impact on the next quality of the next oil change you will receive.
First of all it's not your fucking business when I log in on here and in what manner I write about things on here! What are you? A forum police that you track people down when they login, respond or not respond, cross reference fucking threads (you did it to somebody else I noticed)??? You have an argument post it but don't fucking tell me what I can and can't write about on Christmas Day.
Second, don't think that you are somehow smarter than everybody else and the only one with knowledge of how businesses are run and what actually happens behind "closed doors" at places like barber shops, car shops, small stores etc. I hate to disappoint but you are not (so sorry you're being a princess here thinking that you are special and all that, not me). I can assure you (from first hand experience) that business owners remember clients and will treat some differently to others. For example, an asshole like you would not get any discount at a place I worked at long time ago. On the other hand clients that were pleasure to deal with and spent a lot got their coffee, discounts etc. and in some cases were served after hours.
Finally, 95% or so of people would never tip if it wasn't customary, it's just so counter intuitive and senseless when you already paid for goods/services. Including that tip step in POS is an element that helps sales people sell POSs by advertising that feature and telling the owner that it could bump up revenue (again, first hand experience as I was on the other side of the counter when the guy tried to sell one!!!).
So there, I read your post, strikes me as something an insecure 15 year old would write.
