Most common pet peeve I have is the “With Cheese na po?” aggressive marketing con that they pull. Although, Jollibee, McDo and other chains do this as well…
There are so many people in Sbarro’s that are shocked to find out that the cheese for their pasta was actually extra and had to pay an obscene amount for it when they reach the cashier. At this point in time, they just suck it up (literally, pun intended) as the cheese has been slobbered all over their plate and “nakakahiya na papalitan or di bayaran”. If you feel heroic, next time the server offers you anything…please make sure to ask in a loud manner “May extra bayad ba yan?”, you will save some poor Lola or Lolo in line some of their money and dignity by doing so. Better yet, report this to DTI or Better Business to have these unethical practices checked.

We had also encountered hair and other threads(from God knows where) included in our food – mostly the pasta. Out of 3 times this had happened, the managers at least replaced the food BUT DID NOT OFFER ANY FORM OF APOLOGY.
Moreover, I had seen at least 2 instances of people slipping due to wet floors near the cooler, and chairs/tables being swapped without asking the customers if they are using it. These things aren’t so funny when you’re holding their small trays and uber heavy plates in your hand.

In the US, this kind of behavior invites lawsuits. Ahhh, ya gotta love the Philippines.
A shame that Sbarro’s serve decent deep dish pizzas, but the horrible service ruins everything. Caveat Emptor.
