Was I having a "conservative" moment ?

Earlier today I called a nail salon I used to frequent about a manicure this week. Since today was a holiday here, I figured it might be closed and I’d leave a message about going in on Tuesday. But they were open, and someone answered. I wasn’t prepared to go in, so I asked about Tuesday.

"Sorry, we’re closed tomorrow."

"Oh, okay," I replied. "Funny, todays the holiday."

"What holiday ?" She asked.

"Memorial Day".

"Oh," she replied, dismissively. "We don’t really care about that. We’re Vietnamese."

Stung, I thought, but you live and have your business here. I bit my tongue and didn’t say it, though.

She asked if I wanted an appointment on Wednesday; I told her I’d call again and hung up. She’s not the shop owner, so I might still go. 🙁
