Answer:
Be polite.
Explanation:
As the saying goes, kill them with kindness. If someone is being impolite, either 1, look at the situation i their shoes. Or 2, just simply keep on your professional face, don't lash out, don't act with hidden violence (Etc; slamming money on the counter for them to grab) Just simply apologize and continue working. You're only there for money, or to just have fun, or any reason at all. There's no need to have one person ruin you're mood.
I had to do a bit of research for this one but here is how I would explain it:
In the 17th century, religion was far more important than it is today. It was a vital part of everyday life. Dutch artists would be influenced by the church of England as their artwork, the Church argued, played a key role in guiding the faithful. Art was certainly as important as the written or spoken word - not locked behind any language barrier - and anyone could understand it. Dutch artists had to make their art persuasive: it had to move the faithful (and disbelievers) to feel the reality of Christ’s sacrifice, the suffering of the martyrs, the visions of the saints.
