What bugs me? To name but a few:
"Eatery" really grinds my gears. It's such an ugly, inelegant word. Someone took a perfectly good verb and mercilessly hacked into an noun. Ugh. It supplants lovely and usefully descriptive words like: restaurant, trattoria, cafe, coffee shop, deli, bistro, brasserie, pub, bar, noodle bar, sushi place, steak house, grill, cafe and diner. Places I'd look forward to.
"Simply put" is an insult dressed up as "trying to be helpful". Do I look like I need things "simply put"?
"To name but a few" really bugs me too. It's pompous sales patter. Nobody talks like that in real life.
