I'd booked a meal tonight in a tier 2 restaurant. One bubble. This was clarified when I'd phoned earlier in week.
We arrived in 4 cars for various reasons.
The Front of house politely questioned how we could come 4 cars and still be in one bubble. 
I have utmost of respect for the work hospitality staff do (I work similarly) but it's not their role to police our journeys.
AIBU?
