Met David Tennant. Great guy

I Was at work, working the tills specifically when I see a family walking up with a load of items. I readied my work area clearing off anything on the table and greeted them. I start scanning but I think to myself, “the dad looks familiar”. I look up and get a good look and lo and behold, it’s David Tennant with his daughter and wife (I presume). I didn’t want to be weird so I just say “do I recognize you from where I think I recognize you from?”. He says “yeah probably”. Proceed to say I’m a fan and my family loves him and his work. He thanks me. He sees I’ve got a training lanyard on and starts dishing out positive affirmation 😭 what a great guy. I was very nervous that I’d mess something up like leave a tag on accidentally or take too long but he never rushed me, just kept on being nice. After everything was done and payed for he thanks me and says “lovely to meet you”. Been thinking about this interaction for the last few days. I doubt I’ll ever forget 😭
