Unfortunately, not solved. The bar has a separate address for the bill and bartender tips, something I do not have control over.
This is a situation the bar created for themselves. When you pay them in cash do you make 2 different payments, like if your bill is 22 dollars and you want to tip them 5 dollars do you hand them the 22 dollars and wait for them to put that in the register then hand them the 5 dollars, NO most people do not, you hand them the 27 dollars and tell them to keep the change they usually put it in a jar which at the end of the night is split between the workers. They are making you do their job. If it were me, (but I am an asshole) I simply would tell them no i will not pay the tip separately, I can either include your tipin this transaction and you document it, or I can just not tip you at all. How much do you want to bet they will say just include the tip in that transaction sir?
I will also bet the two addresses went to the same wallet just farther showing you, they are making you do their job. Its easier to look at the address at the end of the night and see how many tips came into that address and then distribute them that way rather than look and compare each transaction to see what the tip was. there are a lot of ways the bar can make that happen without inconviencing them or the customer, they just choose not to do thier job. BOTTOM LINE.
