Sound like you've been given freedom, but not quite enough guidance.
Mgt. should tell you how much to pour, and you should stick to that, even if
it appears that all the others are doing different.
Mgt. should provide a bloody price list or till training to tell you what a
double-up is worth to them.
I know it may seem a bit newbie to ask "How much should I pour?", but it
really should be done. Unfortunately I have once had a manager whose answer
was "About this much" when demonstrating ... into an iced glass yet!
While I too occasionally pay for a customers drink out of my pocket, I get the
feeling from how you describe the conditions that the one that pours big and
"pays it back" ... maybe doesn't. It would be interesting to casually ask mgt.
if you could do the same -
"the same as what?"
"You know, pay back the till $50 or whatever at the end of shift like X does"
"They WHAT?"
- because that's probably theft happening. I know you don't want to rock the
boat, but play it innocent and DON'T fall into those habits!
You've already found that "make it a strong one" is the call of a cheapskate.
My favorite trick is wave the bottle (shake from the neck) while pouring
inverted. Centrifugal force and agitation will make it pour slower, so you
hold the bottle over the glass longer, even though it looks like you are
shaking to get more out.
If someone's begging for a bit more, and I'm not in the mood to explain
economics or the law to them, I may do this to 'top them up', shaking so hard
nothing happens.
The motion distracts them enough to not notice. Then they go away.
