Break in at Penyffordd Post Office

Last night we heard alarms going off at midnight. First checked the car but it wasn't that. Then thought it must be the chip shop or Legion. Turns out a spider had broken into the Post Office. The spider then built a web across one of the sensors.............................
Bit of trouble today being Monday ( internet orders happening all weekend) queue of Ebayers in post office. Alarm automatically locks the safe.........................can't open it.
Where is Mary?

Plenty of grief lined up over post as Postal Worker strike action continues................
