Favoruite Burger on the downside

I like their Big Boss burgers a lot, as it is filling. Gives once satisfaction to the bone but getting the Burger is another case. Try to buy that burger after 6 at night, they are always out of stock or they have ran through their batch for the day.

I shouldn't beg to have one of my favourite burgers, I would highly appreciate it if there could be looked into this. I lost my appetite right there and then, left for something else.
