I came in

Does "I came in" mean to enter to a place, or to arrive to a place?

For me these are two different things, thanks.

"Dear Mr. Ferrell I've been coming to your restaurant ever since you opened. I really love the place, love your ice cream, I love the fun, I love you hamburgers, they are the best! I love your pickles they are the best pickle in seattle. I always asked for an extra pickle they always give me one. Today mr. Ferrell, I came in, had my usual extra, asked for an extra pickle from the young waitress. I don't know where she got the idea but she said: "I'll have to sell you a side of pickles for a 75 cent". That's the way you're going to run your restaurant Mr. Ferrell. I'm not coming back!" Well I got that letter and from an entrepreneur who's just starting on his second store that hurt.
