I will only go to SM if there's no other grocery in the area or if the item I need is not available in my regular grocery. I don't patronise SM malls because they rarely give the exact change. Their grand excuse is that they are out of coins. If this were true, how highly inefficient for a store of their size. In other stores, they give more than the change if they run out of coins.
Plus this practice doesn't only happen for purchases but in bills payment as well!!! They credit the exact amount in the bill even if you give cash over the exact amount. For example if the bill is 1,100.30 and you gave cash of 1,100.50. They will only credit 1,100.30. This happened to me several times so I make sure that I keep coins at home (10 and 5 cents) so I could always give the exact amount. It's not really about the money but the principle behind it.
convenient mag grocery sa sm halos ng kelangan mo meron sila kahit seafood at meat kung bibili ka ng fish pwede mong palinis sa kanila and then madami silang open na cashier kaya hindi masyado mahaba ang pila sa pagbabayad
