I've also experienced this.. in the States! I don't necessarily think the westerners are being disrespectful because they are frustrated at the locals. It's more due to the fact that being disrespectful to workers is common in the States in general. Not as frowned upon. Not that it's ever acceptable here, but point is, I've seen Americans be rude to other American workers. Filipinos in general, are usually, not always, more subdued and willing to be patient with the workers since that's ingrained in Pinoy culture. Not as much anymore, as even Filipinos are starting to westernize. I have definitely seen other Filipinos being rude to local workers in PI as well, but hardly ever. But either way, we should all show some more respect to people and learn to be more patient. Life is too short to get huffy and puffy about things like that.
I would just always re-bag my items in front of them if I didn't like how they did it...they never complained. I was happy, they were happy....
My Filipina wife is much more impatient and demanding about these things than I ever could be, whether we are in the States or the Philippines. She isn't rude or disrespectful about it, but she does want it done the way she wants it done and isn't shy about letting people know that.
While we are talking shop. Putting cheese and uncooked meat in the same bag. Is this hygienic? i never complained, just wondering if this is normal here.
Nothing wrong with letting them know of your displeasure. Many times it is not about what you say, it's more how you say it.
