Pouring Boiling Water Down Kitchen Sink Drain

When we had the new sink drains installed, the plumber said don't pour boiling water down the drain. He said that the plastic tail piece and p-trap connections would fail.

I have always poured boiling water down the sink drain and have never had a problem with it. The new material bought at Lowes does look much more delicate than I remembered seeing in the past and I think it probably is susceptible to heat failure.

Has anyone here poured boiling water into a drain made out of most recent big box drain material? Had any problem with it?
