is the response I most often receive when interviewing people for hospitality work. My guess...you hear it a lot as well. Interestingly, it's not how much you like people that counts most. It's how much people like you.
The most successful people are those which others naturally gravitate toward. The ability to demonstrate care and to deliver it in a meaningful way are extremely powerful. Some of it comes naturally...a friendly smile and positive approach to things. The rest you pick up along the way through experience and mentors...handling unexpected challenges, calm under pressure, etc.
Technical competence is necessary. You don't get far being dumb. But, the highest levels of success are achieved with more than smarts. They're attained by developing relationships, no matter if you're a waiter or a CEO. Hopefully, you have proof how much people have valued your hospitality. Perhaps you have a drawer full of thank you letters, a list of promotions or you can point to comments of appreciation on your Facebook page. Sometimes, it's more subtle...people want to work the same shift as you, or ride on the same bus.
Liking people isn't enough to get by on, especially if no one likes you.
