I go in my local wholefoods store 1-2 times a week every week, usually only once. I go because they stock things my regular supermarket don't and they are things that I need (as a vegan there's certain cheeses and mayonnaise etc that I can only find in there). So basically I go to top up my normal weekly shop. It's in the city centre so some weeks I'm there twice for an appointment or to pick up something i've reserved, to see a friend etc. If i'm there i'll go in to have a look around, see if there's anything I need or fancy. Usually always get something, even if it's only a drink. I last went in on Wednesday because I had a bank appointment so popped in afterwards to get the items I couldn't get on my weekly shop. Today I was in town meeting a friend so went in just as one of the various shops we went in, got my DS a little snack and myself a drink.
Anyway so this is where i'm wondering if i'm strange or not. There's a guy who works in there and either he works every day (I don't go in on the same days every week, it varies) or more likely his shifts always happen to be on the days I go in. We always talk, nothing unusual just normal small talk. But today after he said hello he asked why I come in every day... I was a bit 
and said I don't come in every day! He said 'pretty much' so I made a bit of a joke of it and just said 'I come in once or twice a week, you're acting like i'm obsessed the place!'. He said he just wondered, told me about some offer they had on and walked off.
It really surprised me that he even asked tbh and especially that he thought I was there every day. Sorry, I have a bad habit of overthinking things so this is probably just another example of that but it has bugged me ever since so that's why I needed to ask! I'm just worried now that I come across as strange or sad or whatever because I go in there weekly. I just considered myself a regular customer and didn't think there was anything particularly odd about that.
I know this is silly of me to actually be worrying about it but honestly, I'm wondering if I should stop going now. I also don't think he should have asked anyway, none of his business really is it? I should note it wasn't in a rude tone or anything but he did come over from the work he was doing to ask..
So AIBU to go in so often? Does it make me odd?
