July 29 (Reuters) - Starbucks ( SBUX ) reported a

bigger-than-expected fall in third-quarter global comparable

sales on Tuesday, as the coffee chain operator grappled with

waning demand in a cautious consumer spending environment.

The company saw overall same-store sales decline 2% for the

quarter ended June 29, a sixth straight quarterly contraction.

Analysts on average had estimated a 1.19% dip, according to data

compiled by LSEG.
