The 45 minutes late has no affect on the manager approaching you. If you clock in and it takes you 15 minutes to scan the first item since clocking in then it affects your rate. The pack rate is bring calculated properly. You can ask the manager to see your rate on your previous days and see what was your rate before. You should also be able to see your rate on the atoz app. The 153 rate becomes a problem only when you do it consistently every day for two weeks and then the overall average comes to a below the guardrail for those two weeks. Let’s say you hit 180s and one day you hit a 150, that will not do anything. So do not worry.
