Their patience sorely tested for two sessions, Gloucestershire made hay in the evening sunshine to take control of their LV= County Championship match at Derby.
Both sides were cooped up in their dressing rooms until 1.45pm on the opening day, and attritional home batting soon added to Michael Klinger's frustration as he plotted a second straight victory in the competition.
But the County's skipper and bowlers stuck to their guns, luring Derbyshire into a litany of errors to reduce them to 166 for six at stumps.
A sodden outfield meant the toss could not take place until after an early lunch, with Klinger correctly calling and opting to field first in cloudy conditions.
Former England wicketkeeper Geraint Jones – recruited on a month's loan from Kent – was handed his expected debut and Liam Norwell replaced Matt Taylor in the only other change to the visitors' line-up.
It undoubtedly looked like a seam bowling day, and Derbyshire opener Stephen Moore (1) perished to the 12th delivery of the contest when he nibbled at a full one from Will Gidman and picked out the in-form paceman's older brother Alex at first slip.
Minds may well have been casting back to the opening day of Gloucestershire's previous Championship outing, when a combination of swing and injudicious batting led to an extraordinary clatter of 16 wickets.
But Paul Borrington and Wayne Madsen were in no mood to follow that blueprint, selecting their shots extremely carefully against Will Gidman and new-ball partner James Fuller and content to punish only the bad deliveries thereafter.
Both had strike rates below 40 in the afternoon session, steering their side to 74 for one at tea to seemingly lay a more than handy platform.
Borrington's selfless work was undone in the second over after the resumption thanks to a horrible muddle, as he turned blindly for a third run to Will Tavare at deep midwicket and was belatedly sent back by Madsen – the fielder's whipped throw catching him well short of his ground and sending him packing for 42.
Perhaps still smarting from the confusion, Madsen (33) departed in the next over when he got the faintest of outside edges to Will Gidman and keeper Jones snaffled his first catch in Gloucestershire colours.
That paired Scott Elstone with former County man Marcus North, and the Australian was next to go in amateurish fashion when he shouldered arms to the medium pace of Benny Howell and was unceremoniously bowled.
Often underestimated, Howell struck again via Fuller's simple catch at midwicket to punish Alex Hughes (16) for a non-committal prod.
All of a sudden Derbyshire had slipped to 123 for five, yet Gareth Cross attempted to fight fire with fire when he got off the mark with a straight six off Tom Smith.
The wicketkeeper batsman did not look so clever three overs later when he attempted to club Fuller for a third boundary in succession and was pinned leg before for 15.
