Incorrect schedule time for taking Jacket Potato out of microwave

As per req for Sandwich

> I can make a sandwich in one minute and then I need 30 seconds to serve the sandwich and take money from the customer.

tasks are

```
4:00 serve sandwich 3
4:30 make sandwich 4 <<< make as soon as previous one is served (30 secs from start of serving)
5:30 serve sandwich 4 <<< serve as soon as it is made (1 min)
16:00 take a well earned break! << break as soon as served (30 secs)
```

As per requirement for Jacket potatoes(JP)
> Jacket potatoes are pre-baked but need to be heated in a microwave for 2 and half minutes. I then need 30 seconds to top them and 30 seconds to serve them.

```
0:00 Put jacket potato in microwave
0:01 Make sandwich 1

2:31 Serve sandwich 2
3:01 take jacket potato out of microwave << as soon as SW 2 is served
3:31 top jacket potato << as soon as JP is taken out of MW (30 secs ???)
4:01 serve jacket potato << as soon as topping is done i.e 30 secs
4:31 take a break! << as soon as serving is done i.e 30 secs
```

Looks like putting JP into MW takes only 1 sec but taking JP out takes 30 secs which is not mentioned in the requirement either? Is it deliberate ?
