99.99% bumi are ok. Only few are carrying some sort of thinking. If you are lucky, then you may not met any but if you are in bad luck, then always encounter. My wife's luck is not as good as me. Everyone I met seems to be ok. But end of the day, we can search all races culture in Malaysia, all are telling people to be polite, to be calm (sabar), tolerate, respect people and etc. If we take this into our mind, many misunderstanding can be avoid, especially when facing some so call sensitive issues.
BTW, NEP only favor on elite group. For normal bumi, very less effect. That's why got many non bumi group asked to revise the NEP thing. Not to abolish but cut off the support for rich bumi and focus on poor bumi. Example, when a bumi can afford to buy multi million ringgit house and drive million dollar car, why he should have the bumi discount on other thing? And when got this bumi status, he/she can buy lots of houses/shop lots with 30% discount (maybe share investment with some non bumi friend), then sell out later to earn money. When the house/land in an area have price rise due to these peoples' investment, low income bumi where can bear the cost, even though have 30% discount. Those people who is in the low-mid income, regardless races, all will suffer at the end. When someone put this up, some parties always twist the story and say non bumi attempt to challenge bumi's benefit and etc. And this is prohibited to discuss openly. I think I had reach the limit that allowed. So, you can go figure out and discuss with your friends privately.
