I think you might be a little too sensitive and in all probability I imagine you get offended by the word "dongles" as well. I would recommend descending from your ivory towers for a dose of the real world every now and then lest you lose touch with things that are actually offensive.

Realy with food trucks often serving ethnic food and run/staffed by ethnics.

Yes the term is racist in this case

Uh... no. I have never see this connoted as racist. You don't get to dictate what phrases the public can't use.

Huh? No one is stopping you from saying whatever you want. OP is just offering information about what might come across as racist.

The only person "reading too much into it" is you.
