Why should a quick coffee give you less service than a full meal??

I popped into the Foood at Cresta Shopping Centre for a quick coffee. I frequently visit their franchise in Randridge Mall, and expected the same level of service! I was sadly mistaken, as soon as the waitress heard I was not eating she lost all interest in me, I waited for my coffee, took a while, was then left to fend for myself. Another waitress stopped and enquired if everything was alright, I asked her for my bill, only for her to walk away and do nothing about it. I eventually received my bill, paid and left a tip which I felt should not have even happened. Nevertheless, their was a lady tidying displays and moving around the restaurant (I think the manager) who never once stopped to check on any patrons. Take a lesson from the Foood in Randridge Mall, where the manager is always visible and interested in speaking to his clients.
