I work as the greeter and bag checker in a store and today a big man walked out of the store and his bag beeped. I walked toward him to say we should check it and he walked angrily past me, ignoring me and straight to registers and said "It's not my problem!" and I was so weirded out because most customers are polite. I thought nothing of it, then he went to leave and his bag beeped again, so i said would you like me to check it? and he threw his bags on the floor and said "tell me when you're done." He was very mean and intimidating and walked out of the store to his friends and I stood so shocked, his wife came up to me to see what was beeping, she was nice and i felt so little when i had to bend down and look in the bags even though i couldn't fix the problem, he was so angry and I felt like he did that to make me feel like I was nothing or I worked for him then I went and cried for so long he ruined my entire day. Also I am just 16 and a little emotional. How can I not take things so personally?
