It’s the question that comes up pretty often when dealing with people you do not plan on working with for any longer than a short a while. I’m sure everyone’s encountered it at one point or another.
Now, you need a minor accommodation. You might need your complimentary breakfast coffee in a paper cup instead of crockery. You might want to refrain from shaking someone of the opposite gender’s hand. You might just want to meet someone on a day other than Saturday. Do you:
a. Explain that you are an Orthodox Jew, explain the accommodation you need, why you need it, and end up spending fifteen minutes lecturing someone you will never meet again (even if you are in a rush)
b. Politely ask for the accommodation without providing and explanation, and endure the weird looks or slight annoyance of the person you wish accommodation from
c. Avoid the situation entirely (i.e. do not have complimentary breakfast coffee).
I tend towards a or c in New York, and b or c elsewhere, but I always feel odd or disappointed, no matter which option I choose.
