Today I arrived at work at 7:50 and I still had 10 minutes to enter the convenient applications on the computer, most of the cases were European PIN's with debit and credit cards So what i had to do was to explain to clients how they can solve their problems with their cards, i managed to take some of the clients calls outside the office. And some of our clients were searching for certain services which i got to help them with whatever they needed. Since i had plenty of time i tried to assist some of my collegues at the bank loan office department. ( i hope i was of good assistance👍🏼)

Good job! The phrases “I got to work” and “I arrived at work” have the same meaning here. Do you mean you had work this morning, then it would be “I had to work at 8 and I arrived early at 750”
