I am your bartender, not your grocer

It is one thing to ask for extra tomato, no lettuce, no mayo, sub cheese, or add pickle to your burger, but when you start asking for six pickles to take home for your small cookout you are about to have, that is where I draw the line.
At my bar there is a certain man that comes in literally, every day, we call those customers "regulars." I more than appreciate his patronage, for someone to spend $20 to $30 dollars a day plus tip it goes without saying that it should be appreciated. However, just because you spend your life sucking down brewed hops in hopes to catch a buzz before returning home and permanently indenting your rear-end into my bar stool, does not mean that you have free reign to treat the bar like a grocery store. There is a Giant Eagle about two-miles up the road.
This particular customer reminded me of the popular, "If you give a mouse a cookie" story. If you give a drunk a tomato, he's going to ask for an onion, if you give a drunk an onion, he's going to want "Six pieces of rye bread," if you give a drunk six pieces of rye bread, he's going to want "six pickles." Before you know it, store food counts do not line up and he just may be asking to buy burger patties or lunch meat for his next day's meal.
Now, don't get me wrong, I am all about the "customer is always right" philosophy, but only when the customer is, in fact, right. Small, sports bars like mine thrive on the "regular" customer service. If every one of my "regulars" was given this same treatment, we would run out of stock faster than we usually do (I despise Sundays for this reason).
Yes, we are a restaurant, we are here to serve you. But no, we will not sell you staple food items because you are too lazy to go to the grocery store. Drive the extra two miles and get your "fuel perks." The only "fuel perk" I can give you is another beer to add to your buzz that you will also have to pay for.
